Have you used the has selector in CSS? According to Chris Coyier, it's a game-changer.

[00:00] There's this selector called has in CSS [00:02] and it's just says, does this element [00:05] have within it another absolutely [00:08] arbitrary selector? Like is there a [00:10] check like you can say body has input [00:13] checked? Is there a checked input [00:16] anywhere in the body? Then not only can [00:18] you style the body, but you can then [00:20] continue your selector and then say, [00:22] well, select the footer then and do [00:24] something with the footer. That like [00:25] ability to express that in one statement [00:28] is so powerful that it's like this [00:31] unbelievable what you can do with it. [00:33] And we've gotten it so relatively [00:35] recently that I concerned that a lot of [00:38] people developers don't even know that [00:39] we have it. [00:41] You know, LLMs might not know that we [00:43] have it or or be able to wield it and [00:45] use it in in kind of appropriate ways [00:47] and that's just one thing of a slew of [00:50] other stuff that we've gotten.
