Responsive Web Design
Responsive web design (RWD) is an approach to web design aimed at allowing desktop WebPages to be viewed in response to the size of the device one is viewing with.
A site designed with RWD adapts the layout to the viewing environment by using fluid, proportion-based grids, flexible images, and CSS3 media queries, an extension of the @media rule, in the following ways:
- The fluid grid concept calls for page element sizing to be in relative units like percentages, rather than absolute units like pixels or points.
- Flexible images are also seized in relative units, so as to prevent them from displaying outside their containing element.
- Media queries allow the page to use different CSS style rules based on characteristics of the device the site is being displayed on, most commonly the width of the browser.Responsive web design has become more important as the amount of mobile traffic now accounts for more than half of total internet traffic.
