La pseudo-class CSS :empty representa qualsevol element que no tingui fills. Els fills poden ser nodes d'elements o text (inclosos els espais en blanc). Els comentaris o les instruccions de processament no afecten si un element es considera buit o no.

/* Selecciona qualsevol <div> que no contingui cap contingut */

  background: lime;
}
