We often design a page, design the size of the form, but some time will have something to break through the size of the original table, destroy the overall style of the page, and our hard-designed page is also in the face.
A style sheet can be designed, but only in IE is valid in IE, it is still invalid under Netscape7 and Firefox1, because this is a CSS style set for IE. We can only pray that users don't mess with the content of malicious destruction page.
