::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 …

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 …
:not(:focus):not(:placeholder-shown):invalid, not :invalid

AbortController
One of the new features that was added in Chrome 88 is the ability to pass an AbortController‘s signal into addEventListener. const controller = new AbortController(); const { signal } = controller; document.querySelector(‘…’).addEventListener(‘foo’, (e) => { // … }, {signal}); By calling controller.abort();, you can remove the listener from the event target, just like when …
