:read-only

The :read-only CSS pseudo-class represents an element (such as a locked text input) that is not editable by the user.

/* Selects any <input> element that is read-only */
/* Supported in Firefox with a prefix */
input:-moz-read-only {
  background-color: #ccc;
}

/* Supported in Blink/WebKit/Edge without a prefix */
input:read-only {
  background-color: #ccc;
}

Note: This selector doesn't just select <input>s with readonly set on them; it will select any element that cannot be edited by the user.

Syntax
