You can apply multiple backgrounds to elements. These are layered atop one another with the first background you provide on top and the last background listed in the back. Only the last background can include a background color.

Specifying multiple backgrounds is easy:

.myclass {
  background: background1, background 2, ..., backgroundN;
}

You can do this with both the shorthand background property and the individual properties thereof except for background-color . That is, the following background properties can be specified as a list, one per background: background , background-attachment , background-clip , background-image , background-origin , background-position , background-repeat , background-size .

In this example, three backgrounds are stacked: the Firefox logo, an image of bubbles, and a linear gradient :

HTML

<div class="multi-bg-example"></div>

CSS

.multi-bg-example {
  width: 100%;
  height: 400px;
  background-image: url(https://mdn.mozillademos.org/files/11305/firefox.png),
      url(https://mdn.mozillademos.org/files/11307/bubbles.png),
      linear-gradient(to right, rgba(30, 75, 115, 1), rgba(255, 255, 255, 0));
  background-repeat: no-repeat,
      no-repeat,
      no-repeat;
  background-position: bottom right,
      left,
      right;
}

(If image does not appear in CodePen, click the 'Tidy' button in the CSS section)

As you can see here, the Firefox logo (listed first within background-image ) is on top, directly above the bubbles graphic, followed by the gradient (listed last) sitting underneath all previous 'images'. Each subsequent sub-property ( background-repeat and background-position ) applies to the corresponding backgrounds. So the first listed value for background-repeat applies to the first (frontmost) background, and so forth.
