is there any reason to use grid if you have only one row? I always thought grid was for multiple rows
One thing I find tricky is I'm not totally sure what minmax() or 1fr or auto-fit mean.
Like recently I wrote "repeat(auto-fit, minmax(240px, max-content));" and it works but I don't really get it

really cool to see Blacksky moving further towards having fully separate infrastructure
Bluesky runs an appview.
Blacksky runs an appview.
A complete appview is a several terabytes sized database of the >18 billion follows, likes and posts of all bsky users, ever and forever.
To run a different appview is to make a fork in bsky’s timeline.
One has new posts from Łink.
One doesn’t.

This has all the gnarly details about the Unix terminal that I wish I knew when I started using it. It's weird and kind of wonderful (I talk about why you can use your mouse in the terminal!)
