CSS has Selector

What's new in CSS and UI - IO 2023 Edition

With :has(), you can apply styles by checking to see if a parent element contains the presence of specific children, or if those children are in a specific state. This means, we essentially now have a parent selector.

In this example, an item with a "star" element gets a gray background applied to it, and an item with a checked checkbox a blue background.

PS 1: Don't use :has() at the top of the DOM tree, it can impact performance PS 2: Sadly at the moment Firefox doesn't supports it, only when we active a feature flag
