Can I apply multiple background colors with CSS3?
Yes its possible! and you can use as many colors and images as you desire, here is the right way:
body{
/* Its, very important to set the background repeat to: no-repeat */
background-repeat:no-repeat;
background-image:
/* 1) An image */ url(http://lorempixel.com/640/100/nature/John3-16/),
/* 2) Gradient */ linear-gradient(to right, RGB(0, 0, 0), RGB(255, 255, 255)),
/* 3) Color(using gradient) */ linear-gradient(to right, RGB(110, 175, 233), RGB(110, 175, 233));
background-position:
/* 1) Image position */ 0 0,
/* 2) Gradient position */ 0 100px,
/* 3) Color position */ 0 130px;
background-size:
/* 1) Image size */ 640px 100px,
/* 2) Gradient size */ 100% 30px,
/* 3) Color size */ 100% 30px;
}You can’t really — background colours apply to the entirely of element backgrounds. Keeps ’em simple.
You could define a CSS gradient with sharp colour boundaries for the background instead, e.g.
background: -webkit-linear-gradient(left, grey, grey 30%, white 30%, white);
But only a few browsers support that at the moment. See http://jsfiddle.net/UES6U/2/
