As many popular browsers now allow dynamic generation of their HTML via
to the point where many pages are more an application than a document (often
including the ability to
to make the units map to the
displayed size; or a simple resize of any image map/ image combination
would render it unusable. But even ignoring this;
and looking at an HTML-only browser I still think it should be required that
the units map to the displayed
size or it might not be clear that the units should work with an image even
when it is mapped with a
simple resize using <IMG WIDTH="nn" HEIGHT="nn" > . That is, at a minimum
I should be able to
display the same image file multiple times at different sizes in the same
HTML document and just use the one map (assuming the map uses
percent units). Usage seems much clearer to me; and utility is definitely
betterl and more consistent (in that IMG allows image rescaling but
maps would not). What is the advantage
to leaving it implementation-dependent? That is, I'm having trouble
understanding why a browser would
want to make percent units NOT scale to the displayed size? Do these
browsers also ignore WIDTH and
HEIGHT on the IMG element?
