Question

Trying to scale an image down using the background-size CSS rule but seems to be ignored with Firefox 3.5

CSS

.privatejoker {
    background: aqua url("../styles/images/home-privatejoker.png") no-repeat 0 0;
    background-size: 365px 341px;
    height:341px;
    margin: 0 auto;
    display:block;
    margin-top: -6px;
    }

Answer 1

background-size was added to Firefox 3.6, however the -moz vendor prefix was required.

Since version 4, it is no longer required. If you want to support Firefox 3.6 too, include the vendor prefix in addition to the normal property.
