问题
I need to fill the remaining vertical space of #wrapper under #first with #second div.
I need an only CSS solution.
#wrapper {
width: 300px;
height: 100%;
}
#first {
width: 300px;
height: 200px;
background-color: #F5DEB3;
}
#second {
width: 300px;
height: 100%;
background-color: #9ACD32;
}<div id="wrapper">
<div id="first"></div>
<div id="second"></div>
</div>回答1:
You can do this with position:absolute; on the #second div like this :
FIDDLE
CSS :
#wrapper{
position:relative;
}
#second {
position:absolute;
top:200px;
bottom:0;
left:0;
width:300px;
background-color:#9ACD32;
}
EDIT : Alternative solution
Depending on your layout and the content you have in those divs, you could make it much more simple and with less markup like this :
FIDDLE
HTML :
<div id="wrapper">
<div id="first"></div>
</div>
CSS :
#wrapper {
height:100%;
width:300px;
background-color:#9ACD32;
}
#first {
background-color:#F5DEB3;
height: 200px;
}

You can use CSS Flexbox instead another display value, The Flexbox Layout (Flexible Box) module aims at providing a more efficient way to lay out, align and distribute space among items in a container, even when their size is unknown and/or dynamic.
Example
/* CONTAINER */
#wrapper
{
width:300px;
height:300px;
display: -webkit-box; /* OLD - iOS 6-, Safari 3.1-6 */
display: -moz-box; /* OLD - Firefox 19- (buggy but mostly works) */
display: -ms-flexbox; /* TWEENER - IE 10 */
display: -webkit-flex; /* NEW - Chrome */
display: flex; /* NEW, Spec - Opera 12.1, Firefox 20+ */
-ms-flex-direction: column;
-moz-flex-direction: column;
-webkit-flex-direction: column;
flex-direction: column;
}
/* SOME ITEM CHILD ELEMENTS */
#first
{
width:300px;
height: 200px;
background-color:#F5DEB3;
}
#second
{
width:300px;
background-color: #9ACD32;
-webkit-box-flex: 1; /* OLD - iOS 6-, Safari 3.1-6 */
-moz-box-flex: 1; /* OLD - Firefox 19- */
-webkit-flex: 1; /* Chrome */
-ms-flex: 1; /* IE 10 */
flex: 1; /* NEW, */
}
jsfiddle Example
If you want to have full support for old browsers like IE9 or below, you will have to use a polyfills like flexy, this polyfill enable support for Flexbox model but only for 2012 spec of flexbox model.
Recently I found another polyfill to help you with Internet Explorer 8 & 9 or any older browser that not have support for flexbox model, I still have not tried it but I leave the link here
You can find a usefull and complete Guide to Flexbox model by Chris Coyer here

Flexbox solution
Note: Add flex vendor prefixes if required by your supported browsers.
html, body {
height: 100%;
}
.wrapper {
display: flex;
flex-direction: column;
width: 300px;
height: 100%;
}
.first {
height: 50px;
}
.second {
flex-grow: 1;
}<div class="wrapper">
<div class="first" style="background:#b2efd8">First</div>
<div class="second" style="background:#80c7cd">Second</div>
</div>回答4:
If you can add an extra couple of divs so your html looks like this:
<div id="wrapper">
<div id="first" class="row">
<div class="cell"></div>
</div>
<div id="second" class="row">
<div class="cell"></div>
</div>
</div>
You can make use of the display:table properties:
#wrapper
{
width:300px;
height:100%;
display:table;
}
.row
{
display:table-row;
}
.cell
{
display:table-cell;
}
#first .cell
{
height:200px;
background-color:#F5DEB3;
}
#second .cell
{
background-color:#9ACD32;
}
Example

Have you tried changing the wrapper height to vh instead of %?
#wrapper {
width:300px;
height:100vh;
}
That worked great for me when I wanted to fill my page with a gradient background for instance...
回答6:
All you need is a bit of improved markup. Wrap the second within the first and it will render under.
<div id="wrapper">
<div id="first">
Here comes the first content
<div id="second">I will render below the first content</div>
</div>
</div>

If you don't want to have fix heights for your main-container (top, bottom, ....), you can simply use this css-file to get a flex-container which uses the remaining space incl. working!!! scrollbars

<!DOCTYPE html>
<html >
<head>
<title>Flex Container</title>
<link rel="stylesheet" href="http://demo.qooxdoo.org/5.0/framework/indigo-5.0.css">

.cont{
background-color: blue;
position: absolute;

.footerContainer {

You can just add the overflow:auto option:
#second
{
width:300px;
height:100%;
overflow: auto;
background-color:#9ACD32;
}
回答9:
you need javascript and some client side calculations: http://jsfiddle.net/omegaiori/NERE8/2/
you will need jquery to effectively achieve what you want. this function is very simple but very effective:
(function () {
var heights = $("#wrapper").outerHeight(true);
var outerHeights = $("#first").outerHeight(true);
jQuery('#second').css('height', (heights - outerHeights) + "px");
})();
first it detects the wrapper height, as it is set to 100% it's different everytime (it depends on what screen you are landing).
in the second step it gives the #second div the appropriate height subtracting from the wrapper height the #first div height. the result is the available height left in the wrapper div
