CSS2 Media Types
Media Types allow you to specify how documents will be presented
in different media. The document can be displayed differently on the screen, on
the paper, with an aural browser, etc.
Media Types
Some CSS properties are only designed for a certain media. For example the
"voice-family" property is designed for aural user agents. Some other
properties can be used for different media types. For example, the
"font-size" property can be used for both screen and print media, but
perhaps with different values. A document usually needs a larger font-size on a
screen than on paper, and sans-serif fonts are easier to read on the screen, while
serif fonts are easier to read on paper.
The @media Rule
The @media rule allows different style rules for different media in the same style
sheet.
The style in the example below tells the browser to display a 14 pixels
Verdana font on the screen. But if the page is printed, it will be in a 10
pixels Times font. Notice that the font-weight is set to bold, both on screen
and on paper:
<html>
<head>
<style>
@media screen
{
p.test {font-family:verdana,sans-serif; font-size:14px}
}
@media print
{
p.test {font-family:times,serif; font-size:10px}
}
@media screen,print
{
p.test {font-weight:bold}
}
</style>
</head>
<body>
....
</body>
</html>

See it yourself ! If you are using Mozilla/Firefox or IE 5+ and print this page, you will see
that the
paragraph under "Media Types" will be displayed in another font, and
have a
smaller font size than the rest of the text.
