how to make a div to wrap two float divs inside?
I don't know if it's a common problem, but I can't find the solution in web so 开发者_运维技巧far. I would like to have two divs wrapped inside another div, however these two divs inside have to be align the same level (for example: left one takes 20%width of the wrappedDiv, right one take another 80%). To achieve this purpose, I used the following example CSS. However, now the wrap DIV didn't wrap those divs all. The wrap Div has a small height than those two divs contained inside. How could I make sure that the wrap Div has the largest height as the contained divs? Thanks!!!

Aside from the clear: both hack, you can skip the extra element and use overflow: hidden on the wrapping div:
<div style="overflow: hidden;">
<div style="float: left;"></div>
<div style="float: left;"></div>
</div>
It's a common problem when you have two floats inside a block. The best way of fixing it is using clear:both after the second div.
<div style="display: block; clear: both;"></div>
It should force the container to be the correct height.
This should do it:
<div id="wrap">
<div id="nav"></div>
<div id="content"></div>
<div style="clear:both"></div>
</div>
overflow:hidden (as mentioned by @Mikael S) doesn't work in every situation, but it should work in most situations.
Another option is to use the :after trick:
<div class="wrapper">
<div class="col"></div>
<div class="col"></div>
</div>
.wrapper {
min-height: 1px; /* Required for IE7 */
}
.wrapper:after {
clear: both;
display: block;
height: 0;
overflow: hidden;
visibility: hidden;
content: ".";
font-size: 0;
}
.col {
display: inline;
float: left;
}
And for IE6:
.wrapper { height: 1px; }
Float everything.
If you have a floated div inside a non-floated div, everything gets all screwy. That's why most CSS frameworks like Blueprint and 960.gs all use floated containers and divs.
To answer your particular question,
<div class="container">
<!--
.container {
float: left;
width: 100%;
}
-->
<div class="sidebar">
<!--
.sidebar {
float: left;
width: 20%;
height: auto;
}
-->
</div>
<div class="content">
<!--
.sidebar {
float: left;
width: 20%;
height: auto;
}
-->
</div>
</div>
should work just fine, as long as you float:left; all of your <div>s.
Use this CSS hack, it saved me lot of trouble and time.

I use it in every project.
Here's another, I found helpful. It works even for Responsive CSS design too.
#wrap
{
display: table;
table-layout: fixed; /* it'll enable the div to be responsive */
width: 100%; /* as display table will shrink the div to content-wide */
}
WARNING: But this theory won't work for holder contains inner elements with absolute positions. And it will create problem for fixed-width layout. But for responsive design, it's just excellent. :)
ADDITION TO Meep3D's ANSWER
With CSS3, in a dynamic portion, you can add clear float to the last element by:
#wrap [class*='my-div-class']:last-of-type {
display: block;
clear: both;
}
Where your divs are:
<div id="wrap">
<?php for( $i = 0; $i < 3; $i++ ) {
<div class="my-div-class-<?php echo $i ?>>
<p>content</p>
</div> <!-- .my-div-class-<?php echo $i ?> -->
}
</div>

Here i show you a snippet where your problem is solved (i know, it's been too long since you posted it, but i think this is cleaner than de "clear" fix)
#nav
{
float: left;
width: 25%;
height: 150px;
background-color: #999;
margin-bottom: 10px;
}
#content
{
float: left;
margin-left: 1%;
width: 65%;
height: 150px;
background-color: #999;
margin-bottom: 10px;
}
#wrap
{
background-color:#DDD;
overflow: hidden
} <div id="wrap">
<h1>wrap1 </h1>
<div id="nav"></div>
<div id="content"><a href="index.htm">< Back to article</a></div>
</div>Instead of using overflow:hidden, which is a kind of hack, why not simply setting a fixed height, e.g. height:500px, to the parent division?
<html>
<head>
<style>
#main { border: 1px #000 solid; width: 600px; height: 400px; margin: auto;}
#one { width: 20%; height: 100%; background-color: blue; display: inline-block; }
#two { width: 80%; height: 100%; background-color: red; display: inline-block; }
</style>
</head>
<body>
<div id="main">
<span id="one">one</span><span id="two">two</span>
</div>
</body>
</html>
The secret is the inline-block. If you use borders or margins, you may need to reduce the width of the div that use them.
NOTE: This doesn't work properly in IE6/7 if you use "DIV" instead of "SPAN". (see http://www.quirksmode.org/css/display.html)
HTML
<div id="wrapper">
<div id="nav"></div>
<div id="content"></div>
<div class="clearFloat"></div>
</div>
CSS
.clearFloat {
font-size: 0px;
line-height: 0px;
margin: 0px;
padding: 0px;
clear: both;
height: 0px;
}
