1. No. You define that in an object style.
2. Only if you anchor it to another text frame.
I noticed in your previous thread that you didn't seem to have actually defined any margins. Doing that would help you quite a bit.
Peter, the document has margins (outside larger than inside), although they don't appear on the screenshot I posted. Are you talking about other margins?
No, I was judging by the screen shot. Setting the margins the size of the normal text block and actually snapping everything to them can simplify your life immensely, as can enabling Layout Adjustment (which is now hidden from users in the Liquid Layout panel flyout menu in CS6).
What you say makes sense but I'm not sure how to do it - I use CS5.5 (and am well annoyed that its life was so short with no free upgrade to 6, but that's another discussion )
1) What is the normal text block and how do you set it to margins?
2) The Layout Adjustment dialogue doesn't say anything about snapping?
By normal text block I mean the area occupied by the typical text flow of the document, not including any headers or footers or margin notes.
Layout Adjustment is all about snapping. Do you see the Snap Zone field? That sets how close to a guide an object must be to be considered snapped to it. The rules for waht happens in Layoout Adjustment are very complex, and can sometimes give unexpected results, but in general frames that are snapped to toguides will move and or resize when those guides change. You must enable Layout Adjustment before making the changes.
