These days roughly 50% of all internet traffic is from mobile devices. Therefore it’s critical that your website be properly presented on these devices. The content should be sized and simplified so that it is easily read on small displays such as smartphones and medium displays such as iPads, as well as large desktop displays. This is accomplished by the use of a Responsive design framework. Responsive-based websites automatically detect the display size being used and adjust the content accordingly.
All of my designs are Fully Responsive, meaning that they dynamically optimize presentation for various display sizes; smartphones, tablets and desktop computers.
