Thank you jocelyn for your help on “floats”. You are right when you say that the site loads slowly for a xhtml site.
The truth is, the script behind the site has conditions to validate in xhtml strict and to load without any table, but I didn’t have the time to add content and to validate all in xhtml strict and without tables. It is easier to go xhtml transitional and with tables.
I’m working to validate the site in strict xhtml and table less, but it’s a great headache. It’s easier to add a table than to work with css with div tags. By other side, you need to correct all the affiliate code provided by casinos. For example I can’t use “target=blank”, I have to substitute “&” by “&”, br tags must have a “/” at the end, etc….There is no space for cut and paste.
When I have the time to learn a little more I will try the “floats thing” since I agree that tables is not for layout.
