在我的css代码上我设置了background-image：url

height:100%;

but as a result, the range that the 100% capture is only the size of the screen. if the page have a scroll, all the page line needed to be scroll doesn't appear to have those background.

但结果是，100％捕获的范围只是屏幕的大小。如果页面有滚动，则需要滚动的所有页面行似乎都没有这些背景。

Any suggestions?

有什么建议么？

This is, because 100% means 100% of your parent element. First of all, make sure your document is actually 100% of your browser window.

这是因为100％表示100％的父元素。首先，确保您的文档实际上是浏览器窗口的100％。

html, body {
    width: 100%;
    height: auto !important;
    height: 100%; /* for older browsers */
    min-height: 100%;
}
