Question

Which of the following selects every <p> element that has no children?

(a) :empty

(b) :enabled

(c) :checked

(d) :disabled

The question was asked during an online interview.

My doubt stems from Server Specific CSS topic in section Layout & Images of CSS

Answer 1

Correct option is (a) :empty

For explanation I would say: :empty selects every <p> element that has no children including text nodes, :checked selects every checked <input> element, :disabled selects every disabled <input> element, :enabled selects every enabled <input> element.
