:has() pseudo-class takes a relative selector list as an argument. In earlier revisions of the CSS Selectors Level 4 specification,
:has had a limitation that it couldn't be used within stylesheets. Instead, it could only be used with functions like
document.querySelector(); this was due to performance concerns. This limitation has been removed because no browser implemented it that way. Instead, browsers currently only support the use of
:has() within stylesheets.
