This must be something to do with the 'Style' - I have so far changed the background colour and centred each of the six pages of my site, but I've done it by going to each page separately and changing the page properties.. what is the proper way to make overall changes that affect the whole site?
The layout area is unique to each page - and I have not as yet discovered a quick way of placing the same objects in the same places in each layout apart from:
Creating and positioning the objects that I want to re-use on other layouts, going to Edit and Select All, copying and then pasting onto another layout. It still needs a bit of final positioning, but at least the objects are positioned in relation to each other. There may be a much easier way...
However, the masterborder area is site-wide, unless you rename a particular masterborder (Homepage, Contact, etc.) and use different masterborders for each page. So with this part of the page, you have an easily adjustable choice between a site-wide look for your banners/frames or a more page specific approach.
