Hey, we're back! And a little different than before... css-tricks.com/css-tricks-ha…

CSS-Tricks has a new owner! | CSS-Tricks

Yes, I've got the keys to the castle, so to speak. And, even after 12 years of working on the site, I'll admit I'm a little overwhelmed and nervous about that.

My friend @theo2000 just told me about this new Arc Browser, as a replacement for Google Chrome! After trying it for a day, I gotta say this feels like the future! I'm making the change from Chrome (never thought I would!) Wish me luck!

Replying to @vojta_holik
This is hot. (and nice live specimen harness!) We've been building a broader take on this for ~10mo w/ github.com/GoogleChrome/mode… covering nearly all of these CSS primitives plus 200 more guides across DOM, forms, perf, a11y. To keep it token-efficient we cull all the stuff that models know by default, and then vector search (all local) to pull just the relevant guide. Evals too, ofc. yadda yadda. Anyway. I think you may like it. (And I like what you got here too :)

Pope Leo XIV
@PontifexOct 2
In this era of artificial intelligence, it is becoming urgent to distinguish human art from what machines produce. There is an ontological difference, even before an aesthetic one, between art and what a machine can generate through statistical calculation based on millions of images created by others. Algorithms lack the spark of humanity. For this reason, the Church wishes to renew an alliance with artists and cultural institutions to safeguard our humanity.

love seeing all the #CSS subgrid excitement in my timeline!! def @JoshWComeau inspired 🤘🏻 now that your subgrid interest is piqued, checkout a post I made too‽ maybe even just for the long list of resource examples at the end web.dev/articles/css-subgrid

CSS subgrid  |  Articles  |  web.dev

Subgrid enables grid shareability, allowing nested grids to align to ancestors and siblings.
