Ahhh I see. I *think* that's expected, would you mind trying with two spaces after each line? Certain markdown rendering engines only do line breaks either after two spaces on a line, OR an empty line in between, and that might be why. I did GitHub-flavored which follows that.

CSS Daily - A Daily CSS Challenge A daily CSS challenge - like Wordle, but for CSS!

Watched March MadCSS and thought "what if we could do this every day?"

So I built it. In a day.

cssdaily.dev β€” a daily CSS challenge. Write CSS to match a target, get pixel-diffed in real-time. New challenge every morning.

Scoring adapted from @wesbos.com and @tolin.ski's open-source SynHax.

Hahaha, I do get the sentiment and have been asking internally for us to talk about it more. It's not AI, it's bad timing with technical debt, really. I'm hoping to get out a proper write-up from the team soon to show all the work going on behind the scenes!

I was showing devs how to run coding agents on my work livestream yesterday and asked the chat, "what do you do while your agents are running?" while I wanted for mine to run, and grand majority of the responses were just "this" lol
