Responsive Web Development
Responsive Web Design is a device independent user interface design that aims to develop and deliver an optimized experience on devices with different widths and resolutions: PC, notebook, tablet, smart phone, etc. Responsive web design is a set of techniques used in web development to make the images and layout of a website flexible.
Though the devices may vary but the thing that remains common is a well-designed, fully functional responsive website. In simple words responsive web design can be defined as the approach of designing and developing websites in such a way that they respond to the user's environment and behavior based on orientation, platform and screen size.
