[CSS] Split Content (Float)

See more:

PHP

Hello, this is the first time i use this service, so i'm not sure that [PHP/CSS] is also supported. In Past I use your Site especially for c#,c++ Problems.

My Problem:
I try to split my content in two parts.

CSS:

#content {
          float:auto;
	  background:url(images/zz.PNG) top repeat-x #ffffff;
          padding-top:10px;
          padding-bottom:10px;
        }

#left { 
          width: 69%;
          margin-left:15px;
      }
#right  { 
          width: 20%; 
      }
#left  { float:left;  }
#right { float:right; } 

So It works if I build empty rows

 

 

in backround, else the two parts are totaly overflowed.
Solving the problem with empty rows in backround is very nooby...

So What Can I Do.
