Today with CSS3, you no longer need a background image for gradients. You can use CSS to add a gradient to the background of some elements on your page. For ex.: change the color hex values ("84c8d7" and "327fbd") to the gradient color you need.

	<style>
	/* Source: http://www.apphp.com/index.php?snippet=css-background-gradient */
	.grad{
	background: -webkit-gradient(linear, left top, left bottom, from(#84c8d7), to(#327fbd));
	background: -moz-linear-gradient(top, #84c8d7, #327fbd);
	filter:
	progid:DXImageTransform.Microsoft.gradient(startColorstr="#84c8d7", endColorstr="#327fbd");
	}
	</style>
