    <div style="padding-bottom:0px;padding-left:0px;padding-right:0px;padding-top:0px;top:-20px;left:-960px;" class="sn-simple-logo">
      <div style="1920px;">
        <table border="0" cellspacing="0" cellpadding="0" width="1920" height="685">
          <tbody>
          </tbody>
          <tbody>
            <tr>
              <td><img style="margin:0px;float:none;" border="0" alt="" width="1920" height="685" src="http://img02.taobaocdn.com/imgextra/i2/2090040020/TB23yOIbFXXXXa5XpXXXXXXXXXX_!!2090040020.jpg"></td>
            </tr>
          </tbody>
        </table>
      </div>
    </div>
  </div>
</div>

总结：

1.sn-simple-logo 内涵一个position：absolute 属性

2.top：20px
