# This application demonstrates responsive CSS design principles using
# the media-query mechanism. To run this app:
#
# wapptclsh mediaquery.tcl --server 8080
#
# Then connect various devices to see how their display changes according
# to the viewport size. Or resize the browser window. Or twist the
# handheld device between landscape and portrait modes.
#
# The foreground and background colors change according to the viewport size
# of the device. In a real application, the CSS would be extended to make
# other changes according to the viewport size.
