I checked the XHTML and CSS and they all validate now.
It was a problem caused by the embedded YouTube video, Server Tracker, and I forgot two ALT fields for images. I knew it wasn't big stuff ; P All fixed by changing two files. Now onward...
to the main act, what coding do I actually put on my pages to have them "call" the proper cascading style sheets based on browser?
Warm Regards,
