Responsive website design efficiently scales your websites and applications across multiple devices using a single code base. As a result, your website looks and feels right on desktops, laptops, smart phones and tablets.
Using a responsive framework is cost effective. Instead of developing two different sites, one for desktops/laptops and one for mobiles/tablets a responsive website conforms to the needs of all devices. This results in a quicker development cycle and subsequent cost savings. It’s also easier for you to maintain and better for search engine optimisation. It’s recommended by Google because you only have one set of content, instead of having repeated content on different versions of a site.
