Animated Greyscale to Color Image Reveal Effect
Ana Tudor recently shared a trick on how to make an image partially greyscale: #tinyCSStip Would you like to apply `filter: grayscale(1)`, but only partly, not everywhere? You can emulate that with blend modes. background: url(cat) 50%/ cover, linear-gradient(-45deg, transparent 50%, grey 0);background-blend-mode: luminosity Many variations possible. — Ana Tudor 🐯 (@anatudor) January 20, 2021 …

Don’t use functions as callbacks unless they’re designed for it
Solid advice by Jake: Here’s an old pattern that seems to be making a comeback: import { toReadableNumber } from ‘some-library’; const readableNumbers = someNumbers.map(toReadableNumber); Here’s the problem: // We think of: const readableNumbers = someNumbers.map(toReadableNumber); // …as being like: const readableNumbers = someNumbers.map((n) => toReadableNumber(n)); // …but it’s more like: const readableNumbers = someNumbers.map((item, …

: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 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 → …
