I mostly run Linux and only boot into Windows for games and video editing,
so this site is generally only tested with Firefox and Chrome (which should
also ensure it works on Safari). I know that Internet Explorer does not support CSS3
multicolumn rendering and HTML5 video, but there are no easy ways to work
around those limitations; hopefully Microsoft will add support at
some point.
I also know that some parts of the pages don't work with Javascript disabled,
it's mostly used to add standard menus and footers because the server doesn't
seem to support includes; I'm probably going to switch to preprocessing the
pages when they're installed so that Javascript is no longer required to
do that.
