12. Media: Printing and Other Devices
CSS is more than a language for describing the presentation of pages viewed on desktop browsers (in this chapter referred to as
screen media). By specifying a media type associated with a style block, linked style sheet, or group of rules, you can target other media such as print, mobile devices, and screen readers.
User agents are categorized by their features, or the features of the device they’re running on, into one of several media types. In some cases, such as a desktop browser with a print preview feature, the user agent can support multiple media types; however, only one type will be active at any given time.
