Tips for Liferay Layouts
1. Use Table Based Layouts for Browsers IE 6 & 7 (#if ($browserSniffer.isIe($request) && $browserSniffer.getMajorVersion($request) )
2. Set “main-content” class to be the layout name. That way you can target via CSS when this layout is in use.
3. Remember Layouts can be embedded in a theme or deployed to the entire Liferay Server.
