The problem with hoarding is you end up living off your reserves. Eventually, you’ll become stale. If you give away everything you have, you are left with nothing. This forces you to look, to be aware, to replenish. . . . Somehow the more you give away, the more comes back to you.

:empty

The :empty CSS pseudo-class represents any element that has no children. Children can be either element nodes or text (including whitespace). Comments, processing instructions, and CSS content do not affect whether an element is considered empty.
