Media types 7.1 Introduction to media types One of the most important features of style sheets is that they specify how a document is to be presented on different media: on the screen, on paper, with a speech synthesizer, with a braille device, etc. Certain CSS properties are only designed for certain media (e.g., the 'page-break-before' property only applies to paged media). On occasion, however, style sheets for different media types may share a property, but require different values for that property.

You especially need to configure the viewport if you are designing webpages specifically for iOS. Configuring the viewport is easy—just add one line of HTML to your webpage—but understanding how viewport properties affect the presentation of your webpages on iOS is more complex.
