Examples
Three simple div elements
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>Background-image example</title>
<link href="background-image.css" type="text/css" rel="stylesheet">
</head>
<body>
<div class="one">One</div>
<div class="two">Two</div>
<div class="three">Three</div>
</body>
</html>
The first div has a simple image file applied to it, the second div has a background gradient applied to it, and the third div has both applied simultaneously.
.one {
background-image: url(images/icon.png);
/* here we are applying a single background image to our first block level container element */
/* (could be anything, but it is a div in the live example. */
}
.two {
background-image: linear-gradient(to bottom, #aaa, #eee);
/* Here we are applying a linear gradient to our second block level container. */
}
.three {
background-image: url(images/icon.png), linear-gradient(to bottom, #aaa, #eee);
/* In this case we are applying both the background image and the gradient to our third block level container. */
}
Usage
Background images in general have good support across browsers; there are a few things to take note of, however:
- Older browsers do not support multiple background images, SVG as background images or CSS gradients, so be careful when using these options to make sure that a fallback is provided that will make content readable on older browsers, such as a simple solid colour.
- When using multiple background images, the image at the start of the comma delimited list appears on top of ones later on. This might seem contrary to how CSS is expected to behave.
- Because gradients are still supported in some browsers with prefixes and some not, and some with a slightly older syntax, you should use multiple background gradient properties with different syntaxes, as shown in the below examples.
