Is it possible to add noise to a gradient in CSS?
Here is my code for a radial gradient:
body {
color: #575757;
font: 14px/21px Arial, Helvetica, sans-serif;
background-color: #2f3b4b;
background: -moz-radial-gradient(center 45deg, circle closest-corner, #2f3b4b 0%, #3e4f63 100%);
background: -webkit-gradient(radial, center center, 10, center center, 900, from(#2f3b4b), to(#3e4f63));
}
What would I add to that to have noise on top of it, to give it texture?
It is not possible (even if it was, it'd take a crapton of code tricks to do so) to generate noise textures using CSS alone. There aren't any new CSS3 properties that provide that sort of effect out of the box. A much quicker solution is to use a graphic editor such as Photoshop to do that.
There's no current way in css to add 'noise' to a background.
An alternative solution would be to create a transparent noise png in your graphic editor. Then apply that graphic as a background to a <div>. You would then need to place that <div> over the entire area of the <body> which should then give an appearance of a gradient with noise.
