Media types allow you to define the media to submit documents. Documents can be displayed on the display, paper media, or auditory browsers.
Media type
Some CSS attributes are only designed for certain media. For example, the "voice-Family" attribute is designed for auditory user terminals. Other attributes can be used in different media. For example, the "font-size" attribute can be used for display and print media, but may have different values. The document displayed on the display usually requires a larger font size than the paper media document. At the same time, on the display, the Sans-serif font is easier to read, while on the paper media, the serif font is easier to read.
@ Media rules
@ Media rules enable you to use different style rules for different media in the same style sheet.
The style in the following example tells the browser to display a 14-pixel verdana font on the display. However, if the page needs to be printed, the 10-pixel Times font will be used. Note: font-weight is set to bold, whether display or paper media:
<HTML> @ 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>
