    <h2>Stretched Background Example</h2>
    <p>The background image here has been acheived using an HTML/CSS hack. The page is layered. The image uses the HTML <code>img</code> tag - not the CSS <code>background-image</code> property.</p>
    <p>This text appears in front of the background image. This is because we've used CSS to layer the content in front of the background image. The background image will stretch to fit your browser window. You can see the image grow and shrink as you resize your browser.</p>
    <p>Go ahead - resize your browser!</p>

Answer 2

虽然您可以使用background-size属性very few browsers support it。

如果它是一个小图像（像纹理），你应该使用background-repeat。如果没有，也许使用足够大的图像来覆盖整个div，而不需要拉伸。

可选地，请考虑使用prash详细说明的HTML / CSS hack。

你可以使用重复属性.. background-image:repeat: 除此以外我想你可以用

width:100%;
height:100%;

如何在css属性中拉伸体背景图像取决于内容
