I try to style checkbox background color, but it won't change whatever I do. I am using firefox 29 latest.

Is there some rule changes in css or may be in the browser?

CSS:

input[type="checkbox"] {
    background: #990000;    
}

.chk {
   background-color: #990000;  

}

Here is a demo http://jsfiddle.net/6KXRg/

Can be very simplified like that :

input[type="checkbox"]{
    outline:2px solid red;
    outline-offset: -2px;
}

Works without any plugin :)

Although the question is answered and is older, In exploring some options to overcome the the styling of check boxes issue I encountered this awesome set of CSS3 only styling of check boxes and radio buttons controlling background colors and other appearances. Thought this might be right up the alley of this question.

JSFiddle

body {
    background: #555;
}

h1 {
    color: #eee;
    font: 30px Arial, sans-serif;
    -webkit-font-smoothing: antialiased;
    text-shadow: 0px 1px black;
    text-align: center;
    margin-bottom: 50px;
}

input[type=checkbox] {
    visibility: hidden;
}
