background-size in shorthand background property (CSS3)

Question

I\'m trying to mix background-image and background-size properties in a shorthanded background property. Based on W3C documentation

Answer 1

You will have to use vendor prefixes to support different browsers and therefore can't use it in shorthand.

body { 
        background: url(images/bg.jpg) no-repeat center center fixed; 
        -webkit-background-size: cover;
        -moz-background-size: cover;
        -o-background-size: cover;
        background-size: cover;
}
