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?

此代码工作,但不完全支持:

height: 100svmax;

浏览器支持

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;    
}

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>

在HTML5中,最简单的方法就是设置高度:100vh。其中“vh”代表浏览器窗口的视口高度。响应浏览器和移动设备的大小调整。

简单,只是把它包装在一个表div…

HTML:

<div class="fake-table">
   <div class="left-side">
     some text
   </div>
   <div class="right-side">
     My Navigation or something
   </div>
</div>

CSS:

<style>

 .fake-table{display:table;width:100%;height:100%;}
 .left-size{width:30%;height:100%;}
 .left-size{width:70%;height:100%;}

</style>
