Show Notes // Finds all p tags that have an anchor tag as a child p:has(a) {} // Can find children of parent as well // Finds the button of a paragraph that contains an a tag p:has(a) button {} // Finds all p tags that don't have an anchor tag as a child p:not(:has(a)) {} // Finds all p tags where a is a direct sibling p:has(> a) {} // would find


// would not find


In the past we would write

header p:hover, main p:hover, footer p:hover { color: red; cursor: pointer; }

:where is essentially a short had for making this easier considering the 2nd half of these selectors is the same. Will make your css dryer

:where(header, main, footer) p:hover {}

Also super handy in avoiding css blocks being ignored for unsupported features.

// Doesn't work div:has(p), div:some_new_selector(p) // Will still work for :has if has is supported :where(div:has(p), div:some_new_selector(p)) Tweet us your tasty treats
