// CSS
//
// Notes:
//
// Based on testing with Galeon 1.2.7 (Mozilla 1.2):
// Automatic media-based style selection (via tags) only
// seems to work for the default style, not for alternate styles.
//
// Doing
//
//
//
//
// works to make it so that the printer style sheet get used
// automatically when printing (or print-previewing) a page
// (but when only when the default style is selected.)
//
// Attempts like:
//
//
//
//
// Result in two "Modern" choices when trying to select alternate style.
// If one selects the first of those choices, one gets phpwiki-modern
// both when browsing and printing. If one selects the second "Modern",
// one gets no CSS when browsing, and phpwiki-printer when printing.
//
// The Real Fix?
// =============
//
// We should probably move to doing the media based style
// switching in the CSS files themselves using, e.g.:
//
// @import url(print.css) print;
