If some web sites pages are not rendering properly it might be because your using an older browser.

Older browsers like IE 7, firefox 3.4 and older Opera do not render CSS code. I think all Chromium browsers render CSS properly. The latest version of Safari for Apple/Macs does a good job rendering CSS code. Firefox is downloadable free for windows users.

I am using CSS coding on all the web sites [ EarthBaseZero.net - Maine7.com - SevenRiver.net - MELUG-Central.org ] that I maintain, I use the latest versions of firefox to test my code. I work only in Linux and have no way to test IE.

Only the newer browsers render CSS.
