Re: Focus indicator on image maps

I had not looked at this before, but I tried playing around and couldn't
get anything to work in Firefox either. It seems that the "map" element,
while kind of displayed, is just hanging out dimensionless in the bottom
corner, while the "area" elements are set by Firefox to "display:none", and
my attempts to override that in the Inspector were unsuccessful (despite
using "!important"). Looks like other folks have asked about this in
<https://stackoverflow.com/questions/5026421/apply-css-to-area-map>, where
the answers seem to indicate that it's not possible with CSS alone, and
workarounds suggest using SVG instead, or some jQuery plugins/workarounds
that seem to use the area's coordinates to recreate hover effects (the Map
Hilight one seems to do focus as well).
