<!--[If Lt IE 9]

To determine the browser type:

$.browser.mozilla =/firefox/.test (Navigator.userAgent.toLowerCase ());
$.browser.webkit =/webkit/.test (Navigator.userAgent.toLowerCase ());
$.browser.opera =/opera/.test (Navigator.userAgent.toLowerCase ());
$.browser.msie =/msie/.test (Navigator.userAgent.toLowerCase ());
The expression after the equal sign returns the True/false, which can be used directly to replace the original $.browser.msie.
Check if ie6//oldif ($.browser.msie && 7 $.browser.version) {}//newif (' undefined ' = = typeof (DOCUMENT.BODY.STYLE.M axheight)) {}
Check for IE 6-8
if (!$.support.leadingwhitespace) {}
