html - 高度百分比不起作用

Question

正如您在这个 jsfiddle http://jsfiddle.net/Grek/yLrC8/ 上看到的那样，我尝试将我的文章 DIV 的高度设置为 70%，以便使 DIV 的高度始终等于用户浏览器大小的 70%(但有一个最小高度400px)，但对于某些原因，它不起作用。你知道为什么吗？谢谢

Answer 1

你可以尝试这样的事情:

.article {
    position:absolute;
    text-align:justify;
    width: 450px;
    min-height:400px;
    height:70%;
    right:0;
    padding: 50px 32px 49px 62px;
    margin-right:75px;
    z-index: 15;
    margin-top: 90px;
    background: #ccc;
    overflow-y: scroll !important;
}

通过定位 article absolute，你还可以精确定义你想要它的位置(例如，距离顶部有多远，距离其范围底部有多远)，而不是我现在设置的 float 右:0；。现在您只需要将正确的(您想要的那个)父容器设置为具有一定高度的 position:relative;，这样您就可以使用您想要的那个的 70%。

如果您希望窗口/视口(viewport)在其范围内，您必须将其定位为固定。
