is an approach to web design aimed at crafting sites to provide an optimal viewing and interaction experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from desktop computer monitors to mobile phones).
What’s best for your company :-
Companies need to analyse which devices their target audiences are viewing their website on in order to determine the best design structure of their website. For example, if your customers are not viewing your website on smartphones, don’t bother spending large amounts of money or time on perfecting the responsive design structure and layout for smartphones. In turn, you may believe that due to the increase in smartphone use in the near future, your audience will be using smartphones and in order to stay ahead of the pack, prepare your website for every device.
