1. If the son element is set to float, then set the height of the parent element. This will eliminate the float. However, the general
Do not, the Web page does not set the height.
2. Partition method
Like what
<div class= "Father" >
<div cvlass= "A" > I am a </div>
<div class= "B" > I am two </div>
</div>
The inside of the a.b are set to float. The parent element does not have a height set.
How to solve? Just add a new div between AB, and this div is set to remove the float.

Like what
<div class= "Father" >
<div class= "A" > I am a </div>
<div class= "Al" ></div>
<div class= "B" > I am two </div>
</div>

. al{
clear:both;//Eliminate all floats
}

<div class= "a" >

<div class= "Al" ></div>//Interior wall method is to put AL in the Div.

Overflow:hidden can be automatically propped up by floating sub-elements. This is the so-called folk prescription, indicating that white is the browser rendering mechanism brought.
