For instance, currently you can conditionally change a parent based on its children. For example, this `pre` could either have 16px or 0px of padding. Zero when its direct child is a `code` element.

  pre {
    padding: 16px;

    &:has(> code) {
      padding: 0;
    }
  }

It's a shame that because CSS is still primarily for browser use and styling, we don't get nice things like the ability to select based on text content like we can with XPath. My understanding is that this was proposed but didn't make it into the spec because it could lead to performance issues in a browser rendering context.

It was a joke but I really like the way it pointed out how we copy and reapply patterns in different contexts and that might enable unexpected things.

e.g.:

pyastgrep --css 'Call > func > Name#main'
