Support for Output Devices in CSS
Major way of looking at web pages is via a PC screen, but not the only way
Screen-readers
turn the page into
speech
Mobile devices
have really small screens
Printers
have many different characteristics
Good fonts for print are different from screen fonts
Pages have a fixed size so font-size is likely to use printing conventions
Page width is fixed
Colours on a black and white page don't mean a lot
The
page length
is
fixed
Need to define different styling for different media
