Presentations are one of the best ways to serve information to an audience. The format is short and sharp, made up of small, digestible chunks, which makes any topic under discussion engaging and easier to understand. A presentation can contain all kinds of data, represented by many different elements, such as tables, charts, diagrams, illustrations, images, videos, sounds, maps, lists, etc, all of which lends great flexibility to this medium of expression.

Particularly on the web, presentations come in handy on many occasions, and there are loads of tools at your disposal to create some nifty ones. Today, I’ll introduce you to WebSlides — a small and compact library with a nice set of ready-to-use components, which you can leverage to build well-crafted and attractive web presentations:

WebSlides “is about telling the story, and sharing it in a beautiful way.”

In fact, one of WebSlides’ main benefits is that you can share your story beautifully and in a variety of different ways. With one and the same architecture — 40+ components with semantic classes, and clean and scalable code — you can create portfolios, landings, longforms, interviews, etc.

Besides, you can also extend WebSlides’ functionality by combining it with third-party services and tools such as Unsplash , Animate.css , Animate On Scroll , and so on.

WebSlides is easy to learn and fun to use. Let’s see it in action now.

To get started, first download WebSlides . Then, in the root folder, create a new folder and call it presentation . Inside the newly created presentation folder, create a new file and call it index.html . Now, enter the following code, which contains the needed references to the WebSlides’ files (make sure the filepaths correspond to the folder structure in your setup):

In this section you’re going to create a short, but complete presentation, which explains why SVG is the future of web graphics. Note: If you are interested in SVG, please check my articles: SVG 101: What is SVG? and How to Optimize and Export SVGs in Adobe Illustrator .

You’ll be working step by step on each slide. Let’s get started with the first one.

The first slide is pretty simple. It contains only one sentence:

Each parent <section> inside <article id="webslides"> creates an individual slide. Here, you’ve used two classes from WebSlides’ arsenal, i.e., bg-gradient-r and aligncenter , to apply a radial gradient background and to align the slide content to the center respectively.

The second slide explains what SVG is:

The code above uses the content-left and content-right classes to separate the content into two columns. Also, in order to make the above classes work, you need to wrap all content by using the wrap class. On the left side, the code uses text-subtitle to make the text all caps, and text-intro to increase the font size. The right side consists of an illustrative image.

The next slide uses the grid component to create two columns:

The snippet above shows how to use the grid and column classes to create a grid with two columns. In the first column the style attribute aligns the text to the left (Note how the aligncenter class on the <section> element cascades through to its .column child element, which causes all text inside the slide to be center aligned). In the second column, the browser class makes the illustrative image look like a screenshot.

In the fourth slide, use the grid component again to split the content into two columns:

In this slide, place half of the content to the left and the other half to the right using the content-left and content-right classes respectively:

In this slide, use the background class to embed an image as a background with the Unsplash service . Put the headline on light, transparent background by using the bg-trans-light class. The text’s color appears white, because the slide uses a black background with the bg-black class, therefore the default color is inversed, i.e., white on black rather than black on white. Also, for the text to be visible in front of the image, wrap it with <div class="wrap"> :

In this slide, put the explanation text on the left and the illustrative image on the right at 40% of its default size (with the alignright and size-40 classes on the <img> element). For this and the next three slides, use slideInRight , which is one of WebSlides’ built-in CSS animations:

Do a similar thing here:

This slide also uses a similar structure:

Here, divide the content into left and right again. In the second <p> tag, use the inline style attribute to adjust the font-size and line-height properties. Doing so will override the text-intro class styles that get applied to the element by default. On the right side, use <div class="wrap size-80"> to create a container for the SVG code example:

Here, leverage some of the classes you’ve already used to illustrate browser support for SVG:

In this slide, show some of the use cases for SVG in the form of an image gallery. To this end, use an unordered list with the flexblock and gallery classes. Each item in the gallery is marked up with a li tag:

This section shows a typical SVG workflow, so you need to use the flexblock and steps classes, which show the content as a sequence of steps. Again, each step is placed inside a li tag:

For each step after the first one, you need to add the process-step-# class. This adds a triangle pointing to the next step.

In the last slide, use another one of WebSlides’ built-in CSS animations, i.e., zoomIn :

Congratulations! You’re done. You can see the final outcome here:

Et voilà! You have just created a beautiful, fully functional and responsive web presentation. But this is just the tip of the iceberg, there’s a lot more you can quickly create with WebSlides and many other WebSlides features which I didn’t cover in this short tutorial.

To learn more, explore the WebSlides Components and CSS architecture documentation , or start customizing the demos already available to you in the downloadable folder.

Then, focus on your content and let WebSlides do its job.

Create Incredible Web Presentations with Reveal.js

Feb 24, 2023 · 12 min read

Reveal.js is an open-source HTML presentation framework. Anyone with a web browser can use it to make attractive presentations for free. The program allows anyone with a web browser to create fully-featured and interactive presentations that support CSS 3D transforms , nested slides, and a variety of other capabilities. It is recommended for those interested in programmable techniques and web technology.

It has lots of benefits. Some of these consist of the following:

• Haiku Deck : A web-based application that enables users to design minimalistic presentations with spectacular visual effects.

Getting Started

In this session, we’ll use Reveal.js to create spectacular presentations by utilizing JavaScript. In this section, we’ll learn everything we need to know to get Reveal.js running on our project. To write code to create stunning presentations, let’s first understand the basic setup and installations before using Reveal.

Installations

The best way to install Reveal.js is to clone the source code on GitHub. Utilizing this is extremely simple for you. Just use the code below in your terminal to clone the GitHub repository.

Run the following command to install all the necessary packages and start Reveal.js after you’ve cloned the repository for it in your working directory.

Furthermore, once Reveal.js has been successfully installed in your project, you must start the Reveal.js server on port 8000 (the default port) by executing the following code:

Please use the code below if you decide to run the Reveal.js server on a different port:

You can easily install Reveal.js manually using npm or yarn if you don’t want to clone the GitHub repository:

You may easily include the Reveal.js file as an ES6 module once it has been installed in your front-end framework, such as React:

Folder Structure

This section will go over Reveal.js’ folder structure. When changes are made, the folder structure might change, but this won’t affect how Reveal.js is utilized in our project.

Since we are not the original developers, we won’t be explaining every file in Reveal.js. I’ll go over the most significant directories and files first:

• CSS files that describe how a presentation should appear and be organized are stored in the CSS folder.
• The JS folder houses the JS files that provide interaction and other functionality.
• The presentation begins with a file called index.html that also contains the HTML markup for the slides.
• A reveal.js file contains reveal.js’ setup parameters.

Reveal.js’s folder structure is shown in the image below:

As you can see in the screenshot above, I installed Reveal.js in the opened terminal and launched it by typing npm start .

Starter Template

The starter template is just what is loaded in the index.html page of the Reveal.js folder structure, which we mentioned in the section labeled “Folder Structure” above.

Launch your browser and navigate to the following URLs: http://localhost:8000 The link takes you to the active running page where our presentations will appear in the browser:

This section will concentrate on the contents of Reveal.js. On Reveal Web Presentation, the contents are the components of a responsive presentation. We can use Reveal.js on any project once we have worked with all the components that go into making responsive, stunning presentations, covering Markup, Markdown, Backgrounds, Media, Code Math, Fragments, Links, and Layout.

Markup is the first step in getting started with Reveal.js, and you must use the section element to build markups in Reveal.js. Please remember that the parent class will have the class name . reveal , and the reveal class div will have a child element with the class name .slide . If you place the section element line by line, as in the code below, you will have a slider that moves horizontally.

To make a vertically moving slide, add sections within a section; this is a simple technique; see the code below:

Just use the up and down arrows to view the previous and next slides.

Please use the code below to add a horizontal and vertical sliding format. It’s really simple; the horizontal section of our code will stand alone and not be inside of any section; however, the vertical section will have sections inside of a section.

Backgrounds

It’s simple to add a background color to a slider in Reveal.js; all you have to do is include an attribute that initializes the color for a specific area. You can use the data-background-color attribute to add a background color to a section and specify the value to any color name you choose. View a responsible slider with background colors by referring to the code and outputs below.

Click here to read more about background colors in Reveal.js.

In Reveal.js, media can be used as a presentation. We’ll be showing a video as a presentation in this section. The data-autoplay autoplay attribute must be included in the video tag as an attribute to make the video play when its slide section is open. Code:

You can present codes on the slide and have the code highlighted using Reveal.js. Highlight.js is the only thing that powers the code highlight. You will always use the <code> element when presenting code in Reveal.js, and all you need to do to make HTML escape the default behavior and treat the content as genuine code. Add the data-line-numbers attribute to the <code> element and specify values that will represent the line of code that will be highlighted, as shown below.

In Reveal.js, mathematical expressions can be displayed. To use math in your presentation, you must include the RevealMath.KaTeX plugin, which will reflect the math in your presentation.

Let’s run The Lorenz Equations as a presentation:

The Lorenz equations are a set of partial differential equations that describe two-dimensional fluid flow. Please click here to learn more.

On a slide, fragments are utilized to draw attention to or gradually reveal specific parts. Before moving on to the next slide, each element with the class fragment will be stepped through.

Please include the data-fragment-index attribute and set its value to a number if you wish to use fragments. The number value indexed 1 will appear first, followed by the number 2, in that order.

Session Replay for Developers

Uncover frustrations, understand bugs and fix slowdowns like never before with OpenReplay — an open-source session replay suite for developers. It can be self-hosted in minutes, giving you complete control over your customer data

Happy debugging! Try using OpenReplay today.

While watching slides, Reveal.js also simplified things for us. The following slide in a presentation can be easily reached by clicking a link , and the previous slide can likewise be reached by doing the same.

If you want to navigate to a slider, be sure that the portion of the slider you are visiting has an Id that matches the value of the “href” attribute on the HTML anchor element that is now being clicked.

To instantly navigate to the first page of the slide without passing through any intermediary sections, add ”#/0” (0 == first-slide) to the clickable link that will take you to the first page of the slide.

This section will go over the layout in Reveal.js. You can change the text size, and you can also construct a slide by showing an item on top of the previous item; this is known as staking.

Let’s practice stacking by simply laying images on top of one another.

Now that we understand how stacking works, let’s spend some time working with FIT TEXT. We’ll display some text in a responsive large format in this part under layout by simply utilizing the class name r-fit-text. Below is a code sample of big text applied to Session Replay:

Please note that you can move forward and backward with the arrow keys.

Customization

In this section, we’ll customize some of Reveal.js’s presentations, focusing on Themes and Transitions, the two most significant things to consider while working with Reveal.js.

Theming is essential for creating anything on the internet. In Reveal.js, you can integrate some theme collections supplied by Reveal.js developers.

To use a theme of your choice, import the theme’s CSS styles into your project. The default theme is black when you install reveal.js or clone the Reveal.js repository. A line of code for incorporating a theme into your project is provided below:

Look closely at the code above; you can see where I wrote theme-name ; please replace it with any of the theme names listed below:

• Black (default)

Below, I used a theme name titled sky on a slide:

Utilizing the dracula theme produces the theme below:

Now that we’ve learned more about theming , I’d like you to experiment with different theme names to see how they look on your web presentation slide.

Transitions

Reveal.js provides us with some amazing transition effects to use while making a presentation on the web. It is quite simple to use these transition effects , and some of these transition effects include:

To use these effects, insert a data-transition attribute into your HTML element and set the attribute’s value to the name of the transition effect listed above.

That’s all for transitions in this section; if you want to learn more about Reveal.js transitions, please click here .

We’ll go through presentation features in Reveal.js, such as vertical slides and auto-slide in this section, and since we’ve already covered the implementation largely on vertical slides, we’ll go over more in depth. Let’s get started.

Vertical Slides

Moving between slides by default employs a horizontal sliding transition. These horizontal slides are the main or top-level slides in your presentation. We can’t rely on just one direction in a presentation, and the usage of presenting on slide vertically is critical. We learned how to design a slide that uses vertical direction earlier in this article.

Below is a code sample on utilizing vertical slides:

Auto-Animate

Reveal.js supports auto animation . The auto animate plays a vital role in web presentation. Auto animation applies smooth transition to a slide content, which is noticeable when viewing a presentation. For example, when you set margin-top: 40px to a section, you will see the smooth animation on how the second section comes down slowly. We’ll be implementing some examples here in this section.

To initiate the auto-animate to a section, add the data-auto-animate attribute to the two or multiple sections you want to integrate the auto-animate effect.

The code output above shows that we added margin-top: 100px to the section child (h1) using data-auto-animate , and you can see the effect applied smoothly and removing the default slide horizontal direction to a slightly vertical direction. Please remember that the element in this example is internally hidden but moved using the margin-top attribute. JavaScript will use a CSS transform to achieve fluid movement. Most CSS attributes may be animated and transitioned using the same technique, allowing you to modify positions, font-size, line-height, color, padding, and margin.

We’ll be working on auto-slide in a slide in this section. This is relatively straightforward to accomplish; simply look at our JavaScript code at the bottom of our HTML page and add the autoSlide duration as an integer and set the Boolean value of a loop to true :

JavaScript:

A play/pause icon can be found in the bottom left corner of the slide, as shown in the output above. A round loader describes the progress of the timing function in the icon. The following code is for the output presentation:

Slide Numbers

Numbering is important in slides, and you may add a slider number in two ways: obtain the current slide number and get the slide number and the overall slide count (X/X).

Set slideNumber to true in the config section at the bottom of the HTML page to obtain the real slide number.

Slide Code:

If you look closely at the output above, you will notice a page number counter in the bottom right corner of the screen. When I reached the vertical part while sliding horizontally, the counter format changed to 3.1, which indicates 3 represents the last horizontal slide page and 1 represents the first vertical slide.

To set a slide number in (X/X) format, set your config to the code below:

Please look closely at the bottom right corner of the screen; you will see the page numbering in X/X format. See the code for the output below:

Please, click here to learn more about slide numbers.

Useful hints and guidelines for Reveal.js

In this section, we’ll discover valuable hints and guidelines for working with Reveal.js, which will greatly improve our experience working with Reveal.js for presentation:

• Use keyboard shortcuts to navigate through slides: Use arrow keys or the space bar to move ahead and back through slides.
• Personalize the appearance and feel of your presentation: You can alter the theme, font, and background color of your slides with Reveal.js.
• To add background images to presentations, use the data-background attribute: You can change a slide’s background image by adding the data-background attribute to the slide’ element.
• To set the transition effect between slides, use the data-transition attribute: Transition effects such as ‘slide,’ ‘fade,’ ‘convex,’ and ‘concave’ are available.

I hope you enjoyed this article; we covered everything we needed to know to get started with Reveal.js. We also learned about how to use Reveal.js in our project. There are many more features in Reveal.js, and you can learn more by visiting Reveal’s official website .

How to create a UIKit website: a tutorial for beginners

A Presentation Framework by @marcolago

Press Down Key to continue Or Swipe Up if you prefer.

What is it?

Flowtime.js is a framework for easily building HTML presentations or websites.

It’s built with web standards in mind and on top of a solid full page grid layout.

The animations are managed with native and accelerated CSS3 transitions. Javascript takes care of the navigation behaviour and adds advanced functionalities and configuration options.

Press Down Key or Swipe Up to continue.

Compatibility and Support

Flowtime.js is fully compatible with real moderns browsers:

• Internet Explorer 10

Internet Explorer 9 and some old versions of other browsers lack the transitions and some modern Javascript features but the main navigation and functionalities will work.

In older browsers degrades to a bi-directional scrolling navigation with anchor links.

Touch Devices Support

On touch devices you can navigate through slides swiping in all directions.

By now Flowtime.js was tested and works on Safari Mobile and Chrome Mobile on iOS devices but the support will be wider in the near future.

Mastering the Navigation

You can navigate in many ways. The most common way is using the keyboard.

Navigation Keys and default behaviours:

• Down Key goes to the next page or shows up the next fragment (we’ll see this later).
• Up Key goes to the previous page or hides the fragment.
• Right Key goes to the adjacent page in the next section (if available, it’s like a grid, otherwise it goes to the last page in the next section).
• Left Key goes to the adjacent page in the previous section.

Alternate Navigation Control

Pressing the Shift Key you can alternate the the default navigation keys behaviour; let’s see how:

• Down Key goes to the next page skipping all the fragments.
• Up Key goes to the previous page skipping all the fragments.
• Right Key goes to the first page in the next section.
• Left Key goes to the first page in the previous section.

Some Other Keys

Because: the more, the better.

• Page Up Key goes to the first page of the current section.
• Page Down Key goes to the last page of the current section.
• Home Key goes to the first page of the first section.
• End Key goes to the last page of the last section.

Overview Mode.

You can look at the entire presentation by pressing ESC Key . When in Overview Mode you can go back to the Page Mode by pressing again the ESC Key.

Try it out!

WARNING! Experimental Feature. If you experience problems in webkit browser you can use the alternate Overview Mode; see the documentation for more info.

Navigating the Overview

In Overview Mode the arrow keys works in the same way as in Page Mode, highlighting the future destination. To navigate to the highlighted page just press Return or Enter Key or click on the desired page.

Navigate via Links or Javascript API

You can link every page by simply building the href value using this schema:

Where data-id attribute is an optional attribute you can add to every section or page. I.e.: if you want to go to back to the first page click here (press backspace to come back to this page) .

You can also trigger every navigation behaviour using the Flowtime.js Javascript API . Take a look at the documentation if you want to learn more.

Navigate With History

Flowtime.js offers a full support for the HTML5 History API where available or gracefully degrades on the hashchange event.

This means that you can navigate using the browser’s back and forward buttons and deeplink a page for sharing purposes.

Progress Indicator

You can enable a default progress indicator useful not only to know what’s the current page you are looking, but also as a navigation tool.

Look at the bottom right corner and you can see a miniature of the presentation structure.

Clicking on a page thumb will navigate to that page.

Fragments Support

The built in fragments navigation allows to advance step by step inside a page. Press down to try.

You can discover single elements or even a single part of an element, one at a time.

Fragments navigation is deeply customizable with some configuration options You can learn how in the documentation .

Fragments Unleashed

Thanks to some special classes you can add a couple of useful custom behaviours.

• The .step fragment will partially fades out;
• The .shy fragment will completely hides itself;
• You can use this two special fragment types to easily create special effects.

This is a .shy example!

And this is a .step one!

Default HTML Structures

Flowtime.js comes with a default theme that styles the most common HTML structures, like:

1 st Level Heading

2 nd level heading, 3 rd level heading, 4 th , 5 th and 6 th level heading, unordered lists.

• Another item.
• Just another item.
• Ok, we get it!

Ordered Lists

Definition lists, quotes and citations.

My favourite quotation: The bad craftsman blames his tools .

Sotto un cespo di rose scarlatte dai al rospo the caldo col latte. Sotto un cespo di rose paonazze tocca al rospo lavare le tazze.

Quoting and citing with <blockquote>, <q>, <cite>, and the cite attribute on HTML5 Doctor.

Theme and Styling

If you don’t like the default theme or you want to build your own (or both things), or if you want to build a website on top of Flowtime.js, you can write your own theme and replace the default one.

Theme and core css are in separate files so you can’t break the layout (unless you override some classes).

Fluid Layout

Everything can be fluid, just use em , rem and % units if you want to make an element resizable.

Image Management

Images are fluid like all the other content.

You can insert images in the flow or stack images ones on top the others with a minimal markup overhead to create some fancy fragments tricks.

Go to the next pages to see fluid images in action and how stacked images can be managed, both in the flow or centered in the slide. Look at the source code to learn how to write the markup.

Stacked Images

Centered Stacked Images

About the Centered Stack

You can center anything, not only images!

Just like this content. Useful for splash pages and titles.

And you are not limited to stacks, you can center what you want.

Native Parallax Support

By popular demand Flowtime.js includes native parallax support*.

Simply add a parallax class to anything you want to have parallax enabled and configure the amount of distance for all elements or for a single element using data-parallax attribute.

For an example go to the next page ; for more info read the documentation .

* By the way: I’m not a parallax fan; but ehi… this is the "web 3.0".

The Invaders from Audiogalaxy

This Page Is Just for Testing the Parallax

Code Snippets Highlight

Code highlight is a courtesy of Lea Verou’s Prism . Because I really didn’t want to re-invent the wheel. You can use what you want, it’s not a dependency (but it’s very smart and cool).

Events and Custom Implementations

When navigated to a page Flowtime.js fires a custom flowtimenavigation event full of useful properties to customize or build your components or behaviours.

Read the documentation to learn more about this event and its properties.

Some Examples

You can take a look at some examples to explore some of the possibilities that Flowtime.js offers to customize your experience.

• Cross Direction
• Custom Fragment Animations
• Duplicated IDs
• Modal Overlay
• Page Titles in Navigation
• Scroll the Current Section Only
• Sub Pages Demo

How To Build A Captivating Presentation Using HTML, CSS, & JavaScript

Building beautiful presentations is hard. Often you're stuck with Keynote or PowerPoint, and the templates are extremely limited and generic. Well not anymore.

Today, we're going to learn how to create a stunning and animated presentation using HTML, CSS, and JavaScript.

If you're a beginner to web development, don't fret! This tutorial will be easy enough to keep up with. So let's slide right into it!

We're going to be using an awesome framework called Reveal.js . It provides robust functionality for creating interesting and customizable presentations.

• Head over to the Reveal.js repository and clone the project (you can also fork this to your GitHub namespace).

• Change directories into your newly cloned folder and run npm install to download the package dependencies. Then run npm start to run the project.

The index.html file holds all of the markup for the slides. This is one of the downsides of using Reveal.js; all of the content will be placed inside this HTML file.

Built-In Themes

Reveal includes 11 built-in themes for you to choose from:

Changing The Theme

• Open index.html
• Change the CSS import to reflect the theme you want to use

The theme files are:

• solarized.css

Custom Themes

It's quite easy to create a custom theme. Today, I'll be using my custom theme from a presentation I gave called "How To Build Kick-Ass Website: An Introduction To Front-end Development."

Here is what my custom slides look like:

Creating A Custom Theme

• Open css/theme/src inside your IDE. This holds all of the Sass files ( .scss ) for each theme. These files will be transpiled to CSS using Grunt (a JavaScript task runner). If you prefer to write CSS, go ahead and just create the CSS file inside css/theme.
• Create a new  .scss file. I will call mine custom.scss . You may have to stop your localhost and run npm run build to transpile your Sass code to CSS.
• Inside the index.html file, change the CSS theme import in the <head> tag to use the name of the newly created stylesheet. The extension will be  .css , not  .scss .
• Next, I created variables for all of the different styles I wanted to use. You can find custom fonts on Google Fonts. Once the font is downloaded, be sure to add the font URL's into the index.html file.

Here are the variables I chose to use:

• Title Font: Viga
• Content Font: Open Sans
• Code Font: Courier New
• Cursive Font: Great Vibes
• Yellow Color: #F9DC24
• Add a  .reveal class to the custom Sass file. This will wrap all of the styles to ensure our custom theme overrides any defaults. Then, add your custom styling!

Unfortunately, due to time constraints, I'll admit that I used quite a bit of  !important overrides in my CSS. This is horrible practice and I don't recommend it. The reveal.css file has extremely specific CSS styles, so I should have, if I had more time, gone back and ensured my class names were more specific so I could remove the  !importants .

Mixins & Settings

Reveal.js also comes with mixins and settings you can leverage in your custom theme.

To use the mixins and settings, just import the files into your custom theme:

Mixins You can use the vertical-gradient, horizontal-gradient, or radial-gradient mixins to create a neat visual effect.

All you have to do is pass in the required parameters (color value) and voila, you've got a gradient!

Settings In the settings file, you'll find useful variables like heading sizes, default fonts and colors, and more!

The structure for adding new content is:

.reveal > .slides > section

The <section> element represents one slide. Add as many sections as you need for your content.

Vertical Slides

To create vertical slides, simply nest sections.

Transitions

There are several different slide transitions for you to choose from:

To use them, add a data-transition="{name}" to the <section> which contains your slide data.

Fragments are great for highlighting specific pieces of information on your slide. Here is an example.

To use fragments, add a class="fragment {type-of-fragment}" to your element.

The types of fragments can be:

• fade-in-then-out
• fade-in-then-semi-out
• highlight-current-blue
• highlight-red
• highlight-green
• highlight-blue

You can additionally add indices to your elements to indicate in which order they should be highlighted or displayed. You can denote this using the data-fragment-index={index} attribute.

There are way more features to reveal.js which you can leverage to build a beautiful presentation, but these are the main things which got me started.

To learn more about how to format your slides, check out the reveal.js tutorial . All of the code for my presentation can be viewed on GitHub. Feel free to steal my theme!

I really love reveal.js. I haven't spoken in a while so I haven't used it. I've always used their themes and never thought about making my own. This is probably super useful for company presentations, too. I'm SO over google slides. Trying to format code in those is a nightmare LOL

The best thing in this - and now I'm not being ironic - is that while you work on a not so much technical task - creating a presentation - you still have to code. And the result is nice.

On the other hand, I know what my presentation skills teachers would say. Well, because they said it... :) If you really want to deliver a captivating presentation, don't use slides at all. Use the time to prepare what you want to say.

I'm not that good - yet, but taking their advice, if must I use few slides, with little information on them and with minimal graphical distractions. My goal is to impress them by what I say, not is what behind my head.

I'm going to a new training soon, where the first day we have to deliver a presentation supported by slides at a big auditorium and the next day we have to go back and forget about the slides and just get on stage and speak. I can't wait for it.

How about github.com/team-fluxion/slide-gazer ?

It's my fourth attempt at creating a simple presentation tool to help one present ideas quickly without having to spend time within a presentation editor like Microsoft PowerPoint. It directly converts markdown documents into elegant presentations with a few features and is still under development.

Yup, RevealJS is awesome !

Previously I either used PPT or Google Slides. One is a paid license and the other requires an internet connection.

The cool thing about it is that since it's just HTML files behind the scenes, the only software you need to view it with is a web browser. Has amazing syntax-highlighting support via PrismJS. And as a web developer, it makes it simple to integrate other npm packages if need be...

I actually just used it to present a talk this week!

Check out slides.com If you want to skip the heavy lifting and/or use a presentation platform based on reveal.js.

Everything is still easy to customize. The platform provides a UI to work from and an easy way to share your stuff.

BTW - I have no affiliation with slides.com, or even a current account. I used the service a few years back when I regularly presented and wanted to get over PowerPoint, Google Slides, Prezi, etc.

Thanks for sharing your experience! A business presentation is always done with the aim of conveying key information about your company, products or projects. Regardless of what is being presented or in what format, our goal during the presentation process is to effectively convey ideas about products or solutions. Nowadays, there are really cool advanced solutions for this purpose, such as the Q-NEX control system . This will help you with convenient remote control

How Does It Work?

Slides are basic HTML.

The deck.core module keeps track of slide states and deck states , leaving CSS to define what each state look like…

…and how to transition between them.

Extensions use core events and methods to add goodies , giving presenters the freedom to add what they want and leave out what they don’t.

Creating highly customizable HTML presentations with markdown and pandoc

Update 2021-02-28 : Instead of just having the template I have extracted a markdown-presentation package , which is used by the accordingly updated presentation-template . This allows to adjust styling just once and have it in all my presentations, after updating the package using git submodules. I also got rid of the graphviz integration and adjusted the Makefile , so that dot is only used if the files changed since the last generation, which allowed to shorten the build time by a lot if diagrams have already been generated. Read more about this extraction and the improved build step in another blog .

Warning : This is a rather long blog post explaining also some details. If you are just interested in the end result you might want to jump the the conclusion right away

I love markdown . It’s super easy to write, and also very easy to read, making it a great tool to write e.g. blogs like this one. Since markdown is written using plain text files, it has another bunch of advantages too:

• It can be easily versioned using other tools like git
• It is guaranteed that the content will still be accessible in many years, without worrying about file format incompatabilities
• Tools like pandoc enable us to convert it to many different output files

I have especially fallen in love with pandoc, so that I ended up also writing my master thesis using markdown and pandoc. And of course as a daily GitHub user I am using markdown a lot. It is used when writing issues, PRs, comment on any of these things and even in repositories markdown files are parsed and shown nicely formatted. GitHub has even created its own flavour of markdown and a guide on mastering markdown , another indicator of the importance of this language to this company.

Then I stumbled upon this tweet of Max Stoiber , which sounded interesting. A NPM package that allows to write slides in markdown and afterwards serve them via a webserver using Gatsby under the hood.

How to quickly create a talk from scratch 🔥 Write outline with markdown Install mdx-deck by @jxnblk Add — and in the right places to split outline into slides Done! It does not get faster than presenting your outline 💯 — Max Stoiber ( @mxstbr ) December 1, 2019

First steps with mdx-deck and its obstacles

That sounded great, so I decided to give it a try. The setup went really smooth, and it didn’t take very long to create the first slides. There was an annoying issue that crashed the watch mode , but they seemed to be working on that, so I still decided to give it a try and used it to create the slides for a React lecture I am currently giving. It worked quite well at the start, but it always felt a little bit strange… Probably the weirdest thing for me as a minimalist was that a lot of functionality required to put some JavaScript into the markdown file, which I so desperately wanted to keep clean:

• MDX allows to render React components in markdown
• Using themes requires an import and export statement in markdown

The pure concept of having any kind of code in a human-readable file format — except if the code itself is what you are writing about — gave me a very bad gut feeling. It eliminated 2 out of 3 advantages I initially mentioned! However, I accepted it for quite some time, but then more issues piled up:

• For some reason the watch task only reacted on the first change I made to a file. Subsequent changes were ignored.
• Starting the build or watch task took almost half a minute.
• I was not able to set a padding on code blocks in the presentation. Somehow the used syntax highlighter added some inline styling I was not able to override (not even with !important ).

All of this was very annoying, but embedding images was the final straw. I wanted to do it the markdown way:

But that does not seem to work with mdx-deck. A tool for preparing presentation slides, that did not even support embedding images? To be fair, there was a workaround suggested , but importing the image and writing the img tag on my own in my markdown file was not acceptable to me. I’ve had accepted (for some reasons I don’t understand anymore) the use of JavaScript in other places mentioned above, but using JavaScript to embed an image was just too much for me.

As a JavaScript developer it felt great to use the tools we are using every day to also deliver presentations. But at this point it just seemed way to bloated for a relatively easy task. And then it hit my mind: Why don’t I use pandoc, which I also liked when writing my thesis? So I took about 1.5 hours (right before my lecture) and decided to give it a try. And that was enough time to come up with a solution, that was almost as good as mdx-deck, but I didn’t have to pollute my markdown with JavaScript code. As a nice side effect the complete build of the same presentation takes now 300ms instead of almost 30s (sic!). Minimalism wins again!

Using plain markdown, pandoc and a few lines of code instead

I’ve first had a quick look at the pandoc documentation and found a section about producing slide shows . It supports different ways of creating slide shows, but none of them suited me for different reasons. Especially that most of them couldn’t be installed via a package manager was odd. And I certainly didn’t want to own the code and copy it into my repository. Additionally, when you think about it, producing a HTML slide show is not very hard. Basically it is styling it in some way that a slide fits exactly the size of the screen, and two event handlers to navigate to the next or previous slides. So I’ve decided to build that on my own and published it as a presentation-template on GitHub . I am still going to run through the most important points.

First of all I had to convert the file I called slides.md written using pandoc’s flavour of markdown to HTML. This is as easy as executing the following command — assuming you have pandoc already installed:

The pandoc command takes the name of the markdown file as first parameter, and will automatically recognize to which format it should be converted by checking the file extension of the -o option representing the output file. Usually pandoc would only create a document fragment, but by adding the -s flag it will also include everything a proper HTML document needs, like html , head and body tags. In order to distribute the file without much hassle I have added the --self-contained flag, which will cause to inline all styles and scripts instead of just referencing them. The --section-divs will wrap every header in markdown in a section tag along with its content. So everything until the next heading of the same level will be included in that section . This is an enormous help when trying to style the presentation! Finally the -c option refers to the file containing the CSS, which is called slides.css in my case and does not contain anything except for plain old CSS, and the -A option to inject another HTML file called slides_before_body.html right before the closing body tag. All this HTML file contains is a few lines of JavaScript, which enable the user of the presentation to go back and forth using the arrow keys. For this it will collect all section tags with an id , so that they can be used as an anchor by just setting the fragment of the URL . It will also add an empty fragment as the first available fragment, because the title slide does not get it’s own section .

So by just using three different files ( slides.md , slides.css and slides_before_body.html ) and the pandoc command we already have a pretty nice HTML presentation, which — unless for the HTML markup at which pandoc does an excellent job — we have full control over. There is no third party script adding some inline styles that causes troubles when styling the presentation, and building the presentation is a matter of a few hundreds milliseconds instead of waiting for half a minute. This even makes the watch task obsolete, especially because it is also easily possible to grasp the structure of the presentation when looking at the markdown source as well.

I could have stopped there, but there was one more thing I was really keen on including into my presentation-template, so that I digged bit deeper and invested about 2 more hours: I wanted to be able to include diagrams in my markdown file by using the dot language of graphviz . You can imagine the dot language to be the markdown of diagrams, using an easy-to-write and easy-to-read syntax to describe diagrams. Since it is so easy-to-read, it felt like the perfect candidate for being embedded in markdown. I imagined that somehow like this:

And after asking on StackOverflow if this was possible, I was redirected to the diagram-generator lua-filter . It looked very promising, but it did a little bit more than I needed, and since I like to keep things minimal I’ve copied it and adjusted it:

This code will convert all fenced code blocks with the graphviz annotation you’ve seen in my example above into a SVG string, which in turn can be embedded in the HTML element. Awesome!

All that was left to do was to include this filter in the pandoc command using the --lua-filter option:

Since this command is not that rememberable I went old school and put it into a Makefile . Writing such a Makefile is not that hard, and make is installed on almost every linux machine anyway.

So in conclusion it took me maybe 4 hours to find solution, which is probably less time I already tried to work around some issues of mdx-deck. Summarized this solution also has other advantages:

• Performance is a lot better (build time of 300ms compared to 27s) making a watch task obsolete
• Fully customizable by CSS, with the only conflicts being the ones you generate on your own
• About 20 lines of JavaScript allow to navigate through the presentation using the arrow keys
• About 30 lines of Lua allow to inline graphviz documents and include them as inlined SVG into the presentation

I have to admit that I had to include a few lines of code in the presentation-template, but it is not much. And, more importantly, it is outside of my markdown file, and that’s where it belongs.

Feel free to have a look at my presentation-template and adjust it to your needs.
