Note: The ::-moz-placeholder pseudo-element was introduced as a replacement for the :-moz-placeholder pseudo-class that has been deprecated in Firefox 19.


The ::-moz-placeholder pseudo-element represents any form element displaying placeholder text. This allows web developers and theme designers to customize the appearance of placeholder text, which is a light grey color by default. This may not work well if you've changed the background color of your form fields to be a similar color, for example, so you can use this pseudo-class to change the placeholder text color.


This example styles the placeholder text by making it green.

<!DOCTYPE html>
<title>Placeholder demo</title>

input::-moz-placeholder {
  color: green;


  <input id="test" placeholder="Placeholder text!">


The result looks like this:


bug 737786 - Switch from :-moz-placeholder to ::-moz-placeholder (pseudo-class to pseudo-element)
