Mobile-connected devices have become more common in usage that it has become an issue for displaying the contents in different mobile screen sizes. A need arises for re-coding old HTML such that display is proper in all types of mobile screens.
Independent of Device Type
As a solution to the above problem, responsive web design was introduced which uses the new features in CSS3. The re-coding and positioning are based on screen size, orientation, and pixel ratio. Still the critics remain that these inputs are not enough to determine the device type. But the fact remains that responsive design does not focus on device type. There are plenty of devices with different sizes in the market, and it is practically impossible to create responsive website for all.
Focus on Pixel Dimension
The key behind responsive web design is to focus on content behavior within range of pixel dimensions identifying elements within the design that needs extra attention to fit into other ranges. Thus an alternative version of website for different screen resolutions is built using CSS. The contents are made adaptive to different resolution.
Scale Down to Native Resolution
The viewport meta tag allows to define the pixel ratio while the HD device scales the website down to the native resolution of responsive web design. The devise converts the website display to closest pixel ratio. When the browser window is sized down, the desktop layouts are converted into mobile layouts enhancing the user experience. The responsive web design will update the layout buttons, fields, navigation etc. Even a non-technical person will be able to use the responsive websites comfortably.
