Re: Select element if next sibling

You can read about profiles in the selectors draft..

https://drafts.csswg.org/selectors/#profiles

Basically, selectors are not only used in CSS. In the DOM for example,
querySelector, querySelectorAll and matches all use selectors. Those are
static, one time evaluations on demand. In CSS, rules are applied and
unapplied automatically based on selectors, even during parse.  The latter
is significant more taxing and hard to keep efficient so, something like
:has is easy to implement in the one case, so far seemingly impossible in
the other.
