We still should do more with HTML and CSS! And reach for leaner solutions than React everywhere.
But be careful going for a pure CSS solution for things like tabs if you don’t understand the accessibility requirements.
(I wish the HTML spec would move faster on these common patterns!)
And yes, being able to do all of these in pure HTML/CSS would be awesome. Though we are getting there with things like `details` and the newer `popover` features which should make things like rich tooltips, menu buttons, etc. a lot easier to implement. IIRC, there are also several anchor CSS properties to make positioning a lot simpler.
It's pretty difficult for anyone to completely understand all the nuances in HTML and CSS. It's a big mess that gets bigger and messier every year.
We should have just given JavaScript even more power over controlling the viewport and leave HTML and CSS for the history books.
