Method 1:

height:auto!important; Set the height of the object box without automatic positioning, use !important The height height positioning setting increases the priority;
height:160px; sets the height of the object. Because the attribute !important is used, this attribute is only recognized by IE6.
Method 2:
min-height:160px; Set the minimum height of the object box, applicable to Firefox and IE7+;
height:auto; Set the height of the object box without automatic setting;
_height:160px; Set the height of the object. This property is only recognized by IE6. Under IE6, this property overrides the auto property.

The float attribute cannot be used in the min-height container, otherwise it will be invalid. If used in a large container, float can be cleared internally last, example:

<div id="content">  
  <div id="left"></div>  
  <div id="right"></div>  
 <div class="clear"></div>  
</div>
