HTML page shows warp in IE browser page

When it encounters a normal display under another browser, but the page is deformed under IE, the style style rules have been written well.

This can be caused by the HTML page header specified rule-induced

If the default may be:

<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" >

Just need to change to

<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">

Tell the browser which standards and specifications to use to resolve this page. Whether the standard is met.

Now the display may be normal.
