you're right, of course I should be including my CSS like <LINK
rel='stylesheet' type='text/css' media='screen' href='style3.css'
title='style1'> in the header.
The style3.txt file I was trying to PHP include was there so I could
include more than one stylesheet and make just one amendment. One for
printing and I'm guessing one for mobile. All that file contained was
the <LINK... line above.
That was legacy code. Now I have a furniture object, of course, I can
put my stylesheet code in one place there just as part of the header,
and have no need for style3.txt.
Thanks for all your help.
