Why the ads overlapping?

Hi friends. I added ads to my tag page but ads are being overlaping! I want that they are side by side. How may I do please?

For example;



I want this one;



Thank u.

 

DIV class for your ad

<div class="wrapper">
	        <div class="left">
	            your ad
	        </div>
	        <div class="right">
	            your ad
	        </div>  	       
</div>

Code (markup):

CSS

.wrapper{
   position: relative;
   float: left;
   left: 0.00%;
   width: 200px; /*some px you want */
}
.left{
   position: relative;
   float: left;
   left: 0.00%;
   width: 50.00%;
}
.right{
   position: relative;
   float: right;
   right: 0.00%;
   width: 50.00%;
}
