Question

侧边栏与身体重叠。我需要根据侧栏div和它的背景推动身体div。我有一个jsfiddle链接 link，其中html代码为：

<div class="container">
    <div class="top_block lo2_header">
        <div class="content">
            asdasdfasdfasdfasdfsadfasdasdfasdfasdfasdfsadfasdasdfasdfasdfasdfsadfasdasdfasdfasdfasdfsadfasdasdfasdfasdfasdfsadf<br>
        </div>
    </div>        
    <div>
    <div class="background lo2_lbar">
    </div>
    <div class="left_block lo2_lbar">
        <div class="content">asdasdfasdfasdfasdfsadfasdasdfasdfasdfasdfsadfasda
        asdasdfasdfasdfasdfsadfasdasdfasdfasdfasdfsadfasdasdfasdfasdfasdf<br>
        asdasdfasdfasdfasdfsadfasdasdfasdfasdfasdfsadfasdasdfasdfasdfasdf<br>
        </div>
    </div>
    <div class="background lo2_body">
    </div>
    <div class="center_block lo2_body">
        <div class="content">lo2_body
        asd<br> asd<br>asd<br>asd<br>asd<br>asd<br>asd<br>asd<br>   asd<br>asd<br>asd<br>asd<br>asd<br>asd<br>
        </div>
    </div>
    </div>

    <div class="bottom_block lo2_footer">
        <div class="content">lo2_footer
        </div>
    </div>
</div>
