关于asp.net的一件怪事

Question

asp.net 会修改html代码，导致布局出错，如下代码:
源代码

---

<div id="main"> 
   <div id="show_left" > 
   <br/>
 <uc2:desingerDetail ID="desingerDetail1" runat="server" />
  </div>
  <div id="show_right">
 <uc3:desingerPic ID="desingerPic1" runat="server" />
 </div>
 <uc1:pmdControl ID="pmdControl1" runat="server" PicType="desinger" />
 </div>

生成的代码

<div id="main">
  **<div id="show_left" >** 
  <span>XXXXX</span>
 </div>
</main>

Answer 1

是从浏览器查看源文件看的吗？？？
