Link tags: pseudoclasses

Here’s what I didn’t know about :where() - Manuel Matuzović

I feel like I’m starting to understand how the CSS :where pseudo-class works and why it’s useful. The cogs are slowly turning in my brain.

Can I :has()

This would be such a great addition to CSS—a parent/ancestor selector!

With the combined might of :has(), :not(), nth-child(), and calc(), CSS has become a powerful language for specifying rules to account for all kinds of situations.

Use the :lang pseudo-class over the lang attribute selector for language-specific styles

This is a great explanation of the difference between the [lang] and :lang CSS selectors. I wouldn’t even have thought’ve the differences so this is really valuable to me.

CSS-only multiple choice quizzing - Matthew Somerville

In which Matthew disects a multiple choice quiz that uses CSS to do some clever logic, using the :checked pseudo-class and counter-increment.

[selectors] Functional pseudo-class like :matches() with 0 specificity · Issue #1170 · w3c/csswg-drafts

A really interesting proposal from Lea that would allow CSS authors to make full use of selectors but without increasing specificity. Great thoughts in the comments too.
