Is it possible to change the background graphic for multiple pages without
having to open each one? Thanks in advance.
As other users have pointed out, the answer is "yes", as long as you
haven't built the pages yet. If you are setting up a new site with
multiple pages and you anticipate the need to change the background
image from time to time, a stylesheet will be your answer.
If the pages already exist and you need to change their existing
background image, the answer is probably "no". You may have to deal
with them all individually. You could try opening all the pages in
HTML view and doing a global Find and Replace (Ctrl+H), as long as the
snippet of code for the background is identical in all the pages.
While you're doing that, it might be a good moment to consider
introducing a stylesheet, to allow you to make such site-wide style
changes at some time in the future.
