Our Commentary ​

I always appreciate these CSS roundups from CSS-Tricks. sibling-index() for animations sounds like it could unlock some really dynamic UI patterns without needing JavaScript. And "container stuck queries"? That's a concept I didn't know I needed until now. It feels like CSS is constantly evolving, giving us more power directly in the stylesheet, which is a direction we love.
