Question

尝试将径向渐变设置为bg。问题是，所有其他浏览器都显示渐变，而Firefox则没有。怎么了？在此网站上生成此代码http://www.colorzilla.com/gradient-editor/（支持ie9）

Answer 1

您需要添加以下内容：

html {
    height: 100%;
}

因为body中的所有元素都是绝对定位的，body没有高度。

您已将height: 100%添加到body，但html也没有height，因此height: 100%上body未执行此操作任何东西。

将height: 100%添加到html会使其与视口一样高，因此height: 100%上的body可以正常工作。
