通过ie9获取CSS Div问题

Question

实际上我已经为我的一个游戏网站设计了模板。在我玩游戏的时候我在IE9中遇到了一些问题，但没有其他浏览器的问题。要清楚了解该问题，请参阅this

播放页码：

<div style="float:left">
<div class="gameContentsurround">
<div class="gameContentbg">
       <div class="gameDiv">
          <div align='center'>

            <!--game content here-->        
          </div>
      </div>
</div>
<div class="gameboxbelowheight"></div>
</div>
<div style='height:5px'></div>
<div style="clear:both"></div>
<div class="gameDesc">
<!--game description here-->
</div>
<div class="moregamesbg">
<div class="moregameswhitebg">
<!--more games section here-->
</div>
</div>
</div>
<div style="float:right; width:390px">
 <!--right column where actual issue comes here in IE9-->
</div>

right_column代码：

<div class="playAdsWhiteBg">

</div>
<div style="clear:both"></div>
<div style='height:2px'></div>

<div class="playAdsWhiteBg">
    <div class='playAdsDiv'>
    <center>
        google ads

        </center>
    </div>
 </div>
