Your website should look go no matter what device you are using to view it (desktop, laptop, tablet or mobile phone). That is where responsive design is required. It is a site that uses html and css to determine the device that is viewing the site and then resize and rearrange the site to be viewable on that device. We are not talking about a separate website for each device; rather, responsive design utilizes your web tools to adjust the web page to fit the screen of your mobile device. In fact, search engines such as Google, require responsively mobile optimized sites for today's ranking consideration. Currently, emkay & co designs all their new sites responsive.
