For discussion and questions related to CMS Specific templates and stylesheets (CSS), and themes. or layout issues. This is not a place for generic "I don't know CSS issues"
I am quite new to CMS MS, and I am trying to find out how to customize menu templates. I have made pages based on the CSSMenu Top + 2 columns that came with the package, but I need pages with no columns as well.
I'm presuming that no columns actually means one column.
First duplicate the template: CSSMenu top + 2 columns,
name the new template: CSSMenu top + 1 column (or whatever you like)
in the new template either delete or deactivate the {* Start Sidebar*} through to {* End Sidebar *}
Duplicate the Stylesheet Layout: Top menu + 2 columns
name the new stylesheet whatever you like
in the new stylesheet either delete or deactivate the div#sidebar and it's definitions
and adjust the div#main margins to be equal (the default left margin is 29% and right is 2%)
now connect the stylesheets to the template - I'll leave the rest to you.
CatWoman, as you seem to understand templating, you can do what you want : this is not CMSms specific, just use HTML in HTML templates.
If you have some tag specific issue (parameters, documentation...) please elaborate with an relevant extract of your template.
Have fun with CMSms
