Responsive Web Design – CSS Media Queries

HTML4 and CSS2 currently support media-dependent style sheets tailored for different media types. For example, a document may use sans-serif fonts when displayed on a screen and serif fonts when printed. ‘screen’ and ‘print’ are two media types that have been defined. Media queries extend the functionality of media types by allowing more precise labeling of style sheets.

A media query consists of a media type and zero or more expressions that check for the conditions of particular media features. Among the media features that can be used in media queries are ‘width’, ‘height’, and ‘color’. By using media queries, presentations can be tailored to a specific range of output devices without changing the content itself.

What is Responsive Web Design

Responsive Web Design

Responsive Web Design (RWD) essentially indicates that a web site is crafted to use W3C CSS3 media queries with fluid proportion-based grids, to adapt the layout to the viewing environment, and probably also flexible images. As a result, users across a broad range of devices and browsers will have access to a single source of content, laid out so as to be easy to read and navigate with a minimum of resizing, panning and scrolling.”
