DIV+CSS布局一行两列问题（Repeater布局）

<div>
       <asp:Repeater ID="rptAppReview"  runat =server>
          <ItemTemplate>
            <div>
             <div style="width:80px; height:70px; float :left;clear :both"> 
               <img src="<%#Eval("ScreenshotUrl")%>" alt="" style="width:64px; height :64px" /> 
             </div>
             <div style="float:left">
                 <div style="height :20px"><%#Eval("Title")%></div>
                 <div  style="height :20px">Release date:<%#Eval("PublishTime")%></div>
                 <div style="height:40px; overflow :hidden"><%#Eval("Content")%></div>
             </div>
             <div style="clear :both "></div> <!--清楚浮动-->
          </div>
      </ItemTemplate>
          </asp:Repeater>
    
    </div>
