html中div元素的图像背景
问题描述：
嗨.
我在html页面中有一个"div"元素.div的"width属性"基于百分比，例如"width:80％"，我想将图片设置为div的背景属性.
我有一个宽度为1000px的图像，所以我想图像宽度随div的宽度而变化.
那我该怎么做?

答
如何使用background-size属性?
您可以使背景为拉伸，平铺或都不为背景.查看此属性的"cover"，"contain"和"100％"值.
How about you use the background-size property?
You can have the background either stretch, tile or neither. Look into the ''cover'', ''contain'' and ''100%'' values for this attribute.
