Why Business needs a Responsive Web Design?

Responsive Web design is the approach that suggests design and development should respond to the user’s behavior and environment based on screen size, platform and orientation. Responsive means the website should have the technology to automatically respond to the user’s preferences for mobile devices and desktop resolutions.
Aim of responsive web design is easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices like different mobile devices and desktop screens. Spectrum of screen sizes and resolutions is increasing every day and creating website version for each device is not a practical approach. Responsive web design is collection of technology and ideas.
