我在页面的左侧有一个导航栏,我想让它伸展到页面高度的100%。不仅是视口的高度,还包括滚动之前隐藏的区域。我不想用javascript来完成这个。

它能在HTML/CSS中完成吗?

我也遇到过类似的问题,解决方法是这样的:

#cloud-container{
    position:absolute;
    top:0;
    bottom:0;
}

我想要一个以页面为中心的div高度100%的页面高度,所以我的总解决方案是:

#cloud-container{
    position:absolute;
    top:0;
    bottom:0;
    left:0;
    right:0; 
    width: XXXpx; /*otherwise div defaults to page width*/
    margin: 0 auto; /*horizontally centers div*/
}

你可能需要让一个父元素(或简单的“body”)具有位置:relative;

我遇到了和你一样的问题。我想做一个DIV作为背景,为什么,因为它很容易通过javascript操作DIV。无论如何,我在css中为那个div做了三件事。

CSS:

{    
position:absolute; 
display:block; 
height:100%; 
width:100%; 
top:0px; 
left:0px; 
z-index:-1;    
}

使用表格很简单:

<html>

<head>
    <title>100% Height test</title>
</head>

<body>
    <table style="float: left; height: 100%; width: 200px; border: 1px solid red">
        <tbody>
            <tr>
                <td>Nav area</td>
            </tr>
        </tbody>
    </table>
    <div style="border: 1px solid green;">Content blabla... text
        <br /> text
        <br /> text
        <br /> text
        <br />
    </div>
</body>

</html>

当DIV被引入时,人们非常害怕表格,可怜的DIV变成了隐喻的锤子。

如果你的目标是更现代的浏览器,事情可以非常简单。 试一试:

.elem{    
    height: 100vh;
 }

如果你需要它在页面的50%,将100替换为50。

这就是如何使你的侧导航与页面内容一样高,而不必改变主体为伸缩或表格。

不要将html或body的高度设置为100%,因为那样会使它只和浏览器视口一样高,页面会溢出,而你的导航只会和视口一样高。

只需将你的导航设置为高度:100%位置:绝对与html标签位置:相对。

The reason this works is because height 100% only works if its container is fixed height, with the exception (for some reason) the html tag. <html style='position:relative'> <body style='margin:0'> <div style='height:100%; position:absolute; top:0; background:linear-gradient(to bottom,red,green); border:2px solid blue'> nav </div> <div style='font-size:99px;padding:33px'> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> I want my side div to be as tall as the page content.<br /> </div> </body> </html>
