Hi all, I would like to take advantage of CSSs style features but keep the site looking relatively the same in non css compliant browsers. Is using a server side script like php and outputting html/xhtml based on http_user_agent a useful way of achieving this? (I have seen some Mozilla documentation describing this process as 'ill-advised' - see http://mozilla.org/build/user-agent-strings.html section Cloakers.) Chris.
