La pseudo-class CSS :read-only representa un element (com ara una entrada de text bloquejat) que no és editable per l'usuari.

/* Selecciona qualsevol element <input> que sigui de només lectura Compatible amb Firefox amb un prefix */
input:-moz-read-only {
  background-color: #ccc;
}

/* Compatible amb Blink/WebKit/Edge sense un prefix */
input:read-only {
  background-color: #ccc;
}

Nota: Aquest selector no només selecciona <input>s amb readonly establerts en ells; seleccionarà qualsevol element que no pugui ser editat per l'usuari.
