:where :is :has?

About this presentation

When people say CSS is hard, they often mean that writing good CSS selectors is hard. As a developer, you need to make a lot of trade-offs: a more precise selector also comes with increased specificity, making it hard to overwrite style elsewhere. Targeting two sets of elements often means duplicating the selector and after twentyfive years of CSS, you still can't style based on child elements. ...except CSS now has solutions for all these problems, and more. In this talk we'll explore the impact the new :is, :where and :has pseudo-classes will have on the way you write CSS, how to use some of these features ahead of browser support and the amazing CSS they enable.
