Hypermodern will look a lot like modern, unless you have a good eye and look
for little things. If your browser color defaults are not the page white sort,
this will behave more "purely" in buttons and input fields (in Mozilla, my
buttons are used, not GTK). This supports the Slideshow add-on (all slides in
one long page), which by current code for that plugin means the built in (one
page each) slide-shows are not supported - alas, they use similar CSS tags to
different purposes. There is a very plain sandy gradient behind the top, which
makes it look a bit less silly (although still bulky) if you have a large logo.
Colors are subtle enough for corporate use.
People feeling lost wanting to make their own re-colorations of Modern may
enjoy this heavily commented theme.
