Building my first site in Umbraco, the home page left aligns in IE7/8 and centers as it should in FF and Chrome.
The Umbraco page is http://126.96.36.199/rqhome.aspx
and for comparison, a xhtml/css version is up at http://188.8.131.52/1.html
The non-Umbraco version aligns centered as desired in all test browsers. The Umbraco version centers in all test browsers except IE.
Both rendered pages validate xhtml and css and source code appears to be exactly the same.
Thanks in advance.
