the logic evades me == need education

Indeed, but it's the devices our users use that count not necessarily the devices we actually use.

Absolutely, but from how I read it the op also wants a variant that will work on his/her phone spec.

well . ... was just using my phone as a means to TEST the process
and as I have a samsung 8+with SUPER hi res
(as are most smartphones)
the 'logic' was not logical
it did not work at 800
but does work at 480
and my main resolution is 1000 (my bad -- thought higher in OP)
so from what I think I learned
XARA make the cross over at about 1/2 between the 2 pages
anyway
at 480 -- can now see on my cell
again
thanks to all
