Internet Explorer 8 has three different layout modes.
- Quirks : backwards compatibility with Internet Explorer 5 rendering behavior.

- Internet Explorer 8 Standards : latest features, including the CSS 2.1-compliant layout engine and DOM/HTML breaking changes.
Implement X-UA-Compatible Tag.
- <meta http-equiv="X-UA-Compatible" content="IE=5" /> : Always use IE 5 quirks mode even though site has standards doctype.
- <meta http-equiv="X-UA-Compatible" content="IE=7" /> : Always use IE 7 standards mode even though site has quirks doctype.
- <meta http-equiv="X-UA-Compatible" content="IE=EmulageIE7" /> : Display in IE 7 standards mode unless site has quirks doctype.
- <meta http-equiv="X-UA-Compatible" content="IE=8" /> : Always use IE 8 standards mode even though site has quirks doctype.
- <meta http-equiv="X-UA-Compatible" content="IE=EmulageIE8" /> : Display in IE 8 standards mode unless site has quirks doctype.
- <meta http-equiv="X-UA-Compatible" content="IE=edge" /> : Display in latest mode. In the IE 9 release, this is equivalent to 'IE=9'.
