[英]How to set the last inner div to fill the rest of the wrapper height with CSS?
I would like to create a wrapper div that contains 2 inner divs so that the wrapper and the first inner divs will have a fixed height and the second inner div will fill the rest of the wrapper height. 我想创建一个包含2个内部div的包装div,以便该包装和第一个内部div具有固定的高度,第二个内部div将填充其余的包装高度。
I have done something like this: 我做了这样的事情:
<div class="frameArea">
<div class="header"></div>
<div class="frame"></div>
</div>
My CSS file looks like this: 我的CSS文件如下所示:
.frameArea {
width: 200px;
height: 300px;
border: 2px solid black;
}
.frameArea .header {
background-color: green;
width: 100%;
height: 25px;
font-size: 18px;
line-height: 25px;
}
.frameArea .frame {
background-color: white;
width: 100%;
height: 100%;
}
The thing is, that using this CSS making the .frame div to be 100% of the wrapper's height , which means he will be 300px instead of what i'm looking for - 275px (in this case when the wrapper is 300px and the .header is 25px).
事实是,使用此CSS使.frame div为包装器高度的 100%,这意味着他将为300px而不是我要的值-275px(在这种情况下,包装器为300px且。标头为25像素)。
One way I can do this by setting the height property of .frame using JS code that will calculate and set it dynamically when the document is ready, however I would like to ask if there is any CSS property that does the same in more elegant way? 我可以通过使用JS代码设置.frame的height属性来实现此目的的一种方法,该JS代码将在文档准备就绪时动态地计算和设置它,但是我想问一问是否有CSS属性以更优雅的方式执行相同的操作?
Thanks! 谢谢!
