still new XARA users (after 25 years coding by hand, etc)

made a site with stack rectangles (near to full width of the page)
color-filled them according to the purpose
(eg main header, soft header, text, etc)
was not too hard, until time to edit

for example - want to add/delete text - then I need to edit box size
see the one box with too much grey?
that was result of changing normal font size 16 to 14
(is there a way for the box to auto-size itself?
(sire - I saw AUTO fit - but that reduces font size - I want the box to auto-adjust to the text -
(either bigger or smaller)
and as there are about 20 boxes -
it became VERY tediously a PIA
and will want to insert photos here and there
(either IN some of the text boxes
or
simple rows of photos - maybe even some form of carousel?)
I certainly do not want to drag each box and 'its' text down every time
the first thing that comes to mind is a text box that has background fill? like PPT?
(but could not deduce how to do that)
did try a few times to group the text and its box - then I need to move one item

so
another question ( which would help alot)
is there a way to insert 'anything' (photo, widget, text box etc)
and have all the things auto slide 'down' (like inserting something in a word document?)

thanks!

ps
mostly a single page site (an extra page with navbar)
started with a template
and deleted ALL the items (eg sample text and photos)
