Change select box option background color

Question

I have a select box and I\'m trying to change the background color of the options when the select box has been clicked and shows all the options.

Answer 1

Another option is to use Javascript:

if (document.getElementById('selectID').value == '1') {
       document.getElementById('optionID').style.color = '#000';

(Not as clean as the CSS attribute selector, but more powerful)
