::spelling-error and ::grammar-error pseudo-elements
Part of the CSS Pseudo-Elements Level 4 Specification are ways to style spelling and grammar errors. By default spelling errors — words you have mistyped — get a red dotted underline, thanks to the ::spelling-error pseudo-class selector you can tweak that. Grammar errors — such as a missing capital letter at the beginning of a …
Nice demo by Jhey in which he created a Pure CSS Stopwatch: See the Pen Pure CSS Working Stopwatch 😎 (@property) by Jhey (@jh3y) on CodePen. It uses a clever combination of CSS Animations, CSS Counters, and @property: Each digit gets its own CSS Animation with its own timing. Inside each animation the value of …
Putting libraries like GSAP and Framer Motion and React Spring aside, Josh W. Comeau digs into the transition property — “the CSS motion workhorse” as he calls it — and easing functions. I especially like the sandbox at the very end of the post that lets you play the various easing functions and framerate An …
Dzhavat ran into an interesting performance issue where practically his whole site would repaint when a transition in the header was triggered.

::target-text pseudo-element
One of my favorite features that shipped with Chrome 80 — apart from Optional Chaining — is the ability to link to text-fragments. By default Chrome will highlight those in yellow: 💡 To easily create text-fragment links there’s this Chromium Plugin you can use. ~ As tweeted before, coming to Chromium 89 is the ability …
Cool demo that uses clip-path: path(…);, a feature that recently shipped with Chromium, making it supported in all three major rendering engines. See the Pen About Us Pop-Out Effect by Mikael Ainalem (@ainalem) on CodePen. Peeking under the hood – using the SVG Path Visualizer — you can see that it’s the .container-inner that is …
