In Pro 12.4.1

My web site - www.brownpotters.com - was made with a earlier version of Xara rather then the Pro 12.4.1 I now have and I have not been back to it is some time - years, in fact. There are a couple of things than no longer work and I need to fix/delete them. The version I used did not have the new "one fits all" design for computers, tablets, iphones and I set it up so one must click on a link to move down the pages. I had never pulled it up on an iphone before and when I do so now the first page comes up but none of the navbars work and so no way to get to another page.

I need to re-do the whole site and also build one for my cousin but when I go to the templates in Pro 12.4.1 I see no way to know if a template is set up for one fits all or not. There is one - only one - that says "supersite". I assume it is the only one in my version set up for the new templates. Is this true. Is that the only template I can use or is there a work-a-round to get any web site to fit all the platforms?

Another question, is it better to have the site built so one can just scroll down to the next page rather than the way I have set up my present site where one must click to get to another page?

Tks for the help - jb
