My try on my homepage: http://www.whizzideas.com

XHTML and CSS are two major standard on WWW. But most of the webpages are not XHTML valided or CSS valided. And for most of webpages displayed correctly only in IE, but ugly on Mozilla or Opera. So having a try on XHTML-strict valided and CSS-valided website with compatiability on IE an dMozilla and Opera is rather challenging.
