Stretch and scale a CSS image in the background - with CSS only

Question

I want that my background image stretch and scale depending on the browser viewport size.

I\'ve seen some questions on Stack Overflow that do the job, like

Answer 1

The following CSS part should stretch the image with all browsers.

I do this dynamically for each page. Therefore I use PHP to generate its own HTML tag for each page. All the pictures are in the 'image' folder and end with 'Bg.jpg'.

If you have only one background picture for all pages then you may remove the $pic variable, remove escaping back-slashes, adjust paths and place this code in your CSS file.

html{
    background: url(images/homeBg.jpg) no-repeat center center fixed;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
    filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='images/homeBg.jpg',     sizingMethod='scale');
    -ms-filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='images/homeBg', sizingMethod='scale');
}

This was tested with Internet Explorer 9, Chrome 21, and Firefox 14.
