Thank you very much for your help. I was able (somewhat) to modify the template width from 750px to 960px. When I went into Admin-> Tools-> Template Selection, I was presented with:
Template Language: Defaultt (All)
Template Name: Classic Contemporary Green
Template Directory: cllassic
Under Edit: (only one choice despite the creation of the KQ folder) : Classic Contemporary Green
However, from the above information, I was able to adjust the width in the classic/ccs/stylesheet.ccs and it woked.
A question: why did the system not see the KQ folder?
Another question: how do I make the template width vary according to the computer screen width opened?
Also, there is a couple of side effects, the header background image seemed to be:
Orginal image (750 px, starting from the left) + 1/2 orginal image (to make up for a total of 960px)
A question: how do I change the header background image according to the template width?
In addition, another question about the EZ-Pages header bar or the navigation bar (the bar below the header login bar), I added 6 links/buttons to this bar. The position of the last, final link is on a second row and there is still plenty of space on the first one.
A question: how do I set all 6 links on the same row?
Once again, thank you very much for your help.
