I agree, that does seem to work as expected. I'm not an expert on the
RJS side of things, but I have used Prototype for many years, and $
('foo').setStyle('z-index: 20') certainly works there. Maybe there's
an alternative syntax you could use, where instead of pecking away
with multiple calls to set_style, you could concatenate a hash and
send the whole thing at once, maybe something like foo.set_style {:'z-
index' => 20, :font_size => font_sz, ... }
