CSS Animation Libraries
22.7.2019
There are an awful lot of libraries that want to help you animate things on the web. These aren't really libraries that help you with the syntax or the technology of animations, but rather are grab-and-use as-is libraries. Want to apply a class like "animate-flip-up" and watch an element, uhhh...

Position Sticky and Table Headers
13.7.2019
You can't position: sticky; a <thead>. Nor a <tr>. But you can sticky a <th>, which means you can make sticky headers inside a regular ol' <table>. This is tricky stuff, because if you didn't know this weird quirk, it would be hard to blame you. It makes way more...

Here's a container with some child elements:
<div class="container">
<div>item</div>
<div>item</div>

2.7.2019
Have you ever wanted to ensure that nothing of a (pseudo) element gets displayed outside its parent's border-box? In case you're having trouble picturing what that looks like, let's say we wanted to get the following result with minimal markup and avoiding brittle CSS.

Set Video Playback Speed with JavaScript
2.7.2019
I love that media has moved from custom plugins (Flash…gross) to basic HTML <video> and <audio> elements. Treating these media sources as just another element allows us to use CSS filters to adjust display, for example. The less we need to do with ffmpeg or plugins, the better. I’ve been...

Different Approaches for Creating a Staggered Animation
27.6.2019
Animating elements, at its most basic, is fairly straightforward. Define the keyframes. Name the animation. Call it on an element.
But sometimes we need something a little more complex to get the right “feel" for the way things move. For example, a sound equalizer might use the same animation...

21.6.2019
Did you see that neat technique for using the <picture> element with <source media=""> to serve an animated image (or not) based on a prefers-reduced-motion media query?
After we shared that in our newsletter, we got an interesting reply from Michael Gale:
What about folks who love...
How to Section Your HTML
18.6.2019
The sectioning elements in HTML5 are <nav>, <aside>, <article>, and <section>. <body> is also kind of a sectioning element since all content lying inside of it is part of the default document section.

Detect if Element is a Web Component
5.6.2019
I’ve advocated for web components since before they became a spec, mostly inspired by the Dojo Toolkit’s dijit framework. Empowering first class JavaScript widgets, as opposed to a mess of DIVs and templates, always made the most sense. Now that web components exist, and awesome...
Reducing motion with the picture element
31.5.2019
Here’s a bonafide CSS/HTML trick from Brad Frost and Dave Rupert where they use the <picture> element to switch out a GIF file with an image if the user has reduced motion enabled. This is how Brad goes about implementing that:

Using the Grid Shepherd Technique to Order Data with CSS
28.5.2019
Shepherds are good at tending to their sheep, bringing order and structure to their herds. Even if there are hundreds of those wooly animals, a shepherd still herds them back to the farm at the end of the day.

You can make the text inside any HTML element editable by adding the contenteditable attribute.
<div contenteditable>
Hey, I'm like a textarea kinda now!

The “Inside” Problem
20.5.2019
So, you're working on a design. You need a full-width container element because the design has a background-color that goes from edge-to-edge horizontally. But the content inside doesn’t necessarily need to be edge-to-edge. You want to:
Limit the width (for large screens)
Pad the edges

Footnotes That Work in RSS Readers

Feedbin is the RSS reader I'm using at the moment. I was reading one of Harry's blog posts on it the other day, and I noticed a nice little interactive touch right inside Feedbin. There was a button-looking element with the number one which, as it turned out, was a footnote. I hovered over it,...
