CSS method to select all elements with any id

Question

I want to select all h2 with any id.

I've tried h2#* which is invalid, and I've tried attribute selectors h2[id*=''], but this won't accept a wildcard, and leaving it empty (as above, nothing between the quotes) doesn't match anything.

Is there anything I've missed, or is this just a dead-end?

Answer 1

You can use the attribute selector. It's not necessary to supply a value. This should select all h2 elements with an id attribute, whether or not it has a value:

h2[id] {/* ... */}
