Feedback so far has been really good across several platforms! Also had to push 3 hotfixes already because of broken links and tiny layout issues.

This edition is kindly sponsored by @polypane.app 🫶 The CSS Selection already contained several links to Polypane, even before I decided to accept sponsors. Having @kilianvalkhof.com contact me felt like puzzle pieces coming together. Super stoked and proud!

Question: How is it possible to ship 131mb of css is it like a ton of embedded svgs I guess?

Hey Ben!! 👋 I haven't really looked into that particular case yet. Might do that later today because I'm curious too.

So, I just did and it looks like I made a boo-boo. A recoverable one, but still. There's an error in the scraper that would accept HTML responses as CSS. Luckily this has no impact on any metric apart from file size, but ugh.... Biggest stylesheet I could find now is... only 52.5 MB
