Friends, Responsive web design process is a best way to present a website in all devices computers, laptops, smart phones and tablets beautifully. To design a responsive web design we can use frame works. If we use frame works then we can get predesigned layouts. The popular responsive frame works are: - Bootstrap - Foundation 3 - Skeleton - Semantic I have worked on Bootsstrap, foundation 3 and sematic. Out of these three semantic is easy and better ui it has. Before work with any frame work please read it thoroughly then only get into work and you should have good knowledge on html 5 and css3 to design a responsive website.
