The folks over at Formidable have been experimenting with Houdini and WebGL/Three.js to create futuristic UIs Futuristic sci-fi UIs in movies often support a story where humans, computers, and interfaces are far more advanced than today, often mixed with things like super powers, warp drives, and holograms. What is it about these UIs that feel …
Animating a CSS Gradient Border
Recently, Stephanie Eckles sent out a call to revive the use of CSS border-image. Not to use it with images — which requires a pretty nasty syntax — but to create Gradient Borders in CSS. 🎉 Time to revive an old CSS property! When `border-image` was announced, I was off-put b/c the syntax was so …
:focus-visible Is Here
With Chromium 86 and now recently Firefox 85 supporting :focus-visible, it’s a good time to refer to this post by Matthias Ott: The :focus-visible pseudo-class lets you show focus styles only when they are needed, using the same heuristic that the browser uses to decide whether to show the default focus indicator. You use :focus-visible …
“This website is a single HTML file”
This website is a single HTML file. It simply uses the #anchor suffix (from 1992) and the :target CSS selector to show and hide pages/content. This setup is databaseless, javascriptless, and buildshit-free, so you can edit your website with a text editor and upload it somewhere like a normal person. Brilliant! 🤩 John Doe → …
The Minimum Content Size In CSS Grid
Ahmad recently encountered an issue where a CSS Grid column grew too large: .wrapper { display: grid; grid-template-columns: [main] 1fr [aside] 16em; grid-gap: 2em; } The main column has a 1fr value. That means it will take the available space minus the sidebar and the gap. However, the minimum content size of a grid item …
Form Validation: You want :not(:focus):not(:placeholder-shown):invalid, not :invalid
The built-in browser form validation mechanism can be frustrating as it will mark fields invalid while still entering text. Using only CSS this can be circumvented, so that validations happen afterwards.
Sticky Photostack
Ooh I like this demo, making clever use of position: sticky;: See the Pen Sticky Photostack by Bennett Feely (@bennettfeely) on CodePen. There’s also some clever sizing going on in there to create the whitespace around the images, avoiding the need for a wrapper div per photo. img { width: 100vmin; height: 100vmin; transform: scale(0.6) …
How to render 3D in 2D canvas
Louis Hoebregts walks us through how they rendered a 3D globe on a 2D canvas. Because as all the following animation steps were plain 2D, I couldn’t use a 3D renderer such as Three.js. And so I had to figure out how to render a 3D shape using only the Canvas 2D API. In this …

How to Record Screen Actions as a Puppeteer Script
One of the new (experimental) additions to the Chrome 89 DevTools is the Puppeteer Recorder: DevTools can now generate Puppeteer scripts based on your interaction with the browser, making it easier for you to automate browser testing. Simply start a new recording and as you click around you’ll see Puppeteer code being generated. Stefan Judis …
