Apple 'Broke' Web Apps in iOS 17 Beta; Still Hasn't Fixed Them — There’s been plenty of chatter about App Store changes, and PWAs in iOS 17 this week — all coming as a result of upcoming EU enforcement of the Digital Markets Act. This PWA bust is a change in the current beta, and the overall deadline for DMA compliance is in March — so things may change yet, but right now it’s not looking great for all things PWA on iOS for those in the EU.

The New CSS Math: pow(), sqrt(), and Exponential Friends — These CSS functions are now available in the latest versions of Chrome, Edge, Firefox, and Safari. The pow() function mirrors the Math.pow() JavaScript functionality (for specifying how many times to multiply a number by itself). The sqrt() function is for finding the square root of a number. Dan shares details on these, where you might use them, and more. Handy stuff.

CSS Neural Network (Number Detection) — This is kinda wild, and it feels like magic (but really it's just math!™). You 'draw' in a number and the output updates with its best guess (▶️ Quick video demo). It didn’t work in Safari for me, but seems ok elsewhere. (The true 'magic' here is in the use of SCSS to create a lot of boilerplate – well worth looking through, and then looking at the resulting CSS in DevTools.)
