:has()
Similar to how you can (ab)use :nth-child() to create “new” CSS selectors, you can leverage :has() to create some typical combinators. Brandon McConnell did just that: y:has(+ x) selects the first preceding y sibling of x: y:has(~ x) selects all preceding y sibling of x: x + y, y:has(+ x) selects the first preceding and …

::spelling-error and ::grammar-error pseudo-elements

Especially the different type of attribute selectors are really powerful: // Seven different types of CSS attribute selectors // This attribute exists on the element [value] // This attribute has …

:is() selector will simplify things
One of the selectors in CSS Level 4 is :is(). It is the successor to :any() and :matches() (which are supplanted by :is()): The :is() CSS pseudo-class function takes a selector list as its argument, and selects any element that can be selected by one of the selectors in that list. This is useful for …
