Not sure what you are asking, but there's nothing wrong with the Zeta theme as supplied and it is fully editable and customisable.
If you want to resize the page and rectangle objects without resizing the head and foot text and objects:

Marquee select the head icons / logo type and subtext then move it off the page.

Marquee select the row of buttons / separator line / copyright text and 'Made with Xara' and move them off the page.

Resize the page by dragging the right then bottom edges (or in the page options)

Marquee select all objects *on the page* and drag resize to fit the new page area.

You can then return the off-page objects back to their positions using the same 'marquee-select' method.



Works perfectly and all mouseoff/mouseover actions are retained correctly.

Apologies if I misunderstood.
