Over the last 4-5 years, Responsive Web Design has become quite the hot topic in the web design community.

It’s hard to talk about how important responsive design is, without knowing what exactly responsive web design is? Well, as you know, computers are not the only platform where we can browse anymore. We wants to browse the sites on our phones just as easily as we browse on a desktop or a laptop & it leads web designers to design a websites with their 'mobile' version also as well as their ‘desktop’ version.
So, the purpose of responsive web design is to have one site, but with different elements that respond differently when viewed on different size devices. one need not spend extra time and money in designing & developing  one “mobile-site version” and another “desktop-site version” of their website.
RWD is a quite successful approach where a web designer designed a webpage that responds on the type of devices,it is being seen through from desktop to laptop, smartphone to small notebook.

Additionally, Google also has begun to boost the ratings of sites that are mobile friendly if the search was made from a mobile device.
