How to style Disabled Options in a form

[liaiceags]

I'm using a form with a drop-down menu that contains some options disabled, so the users cannot select them. I'm trying to customize via css these elements but I have some problems with Chrome and IE7/8/9/10. I'm using the following code in my css file:\[code\]select option[disabled] { color: #000; font-weight: bold }\[/code\]This code works only with Firefox and doesn't work with Chrome and IE (all version).Any idea to solve this problem?Thanks in adv.
