I thought it was generally agreed long ago that the best approach was to use :has() rather than a marker in the selector. It's more general and allows more types of things to be expressed. Basically, the subject indicator is exactly equivalent to a :has() pseudo limited to the end of the selector: foo $bar baz {...} == foo bar:has(baz) {...} However, :has() can be placed anywhere in the selector, and so allows more powerful selections: label:has(:checked) + section > p {...} This also has the nice benefit of not using up the $ (or any other glyph) inside of selectors. ~TJ
