CSS Media Types
With media types a page can have one layout for screen, one for print, one for handheld devices, 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>
<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 ! Print this page (or open Print Preview), and 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.
