Sometimes there is a situation, when we don’t have the right background image to cover whole area of site’s window for all resolutions. Here’s a quick CSS reference to make background image resize to whole screen.
background:#233d4b url(../i/bg.jpg) no-repeat 50% 50% fixed; background-size: 100% 100%; -moz-background-size: 100% 100%; /* Firefox 3.6 */ -o-background-size: 100% 100%; /* Opera 9.5 */ -webkit-background-size: 100% 100%;/* Safari 3.0 */ -khtml-background-size: 100% 100%; /* Konqueror 3.5.4 */
This works in all browsers except Internet Explorer, versions lower than 9.
