Valentines:  Design Responsive is now a mandatory part of any web build- its inclusion allows a site’s layout to change as the screen size being used to view the site changes screen>tablet>smartphone. A wide screen display will show a website design that may have numerous columns or panels of content, while a phone screen will have the same content presented in a single column with text and links sized accordingly.

Google sees responsive design as such an important feature for the user experience that last year it added a “Mobile Friendly” label to websites that are responsive and rewards those sites accordingly (improved visibility in its search engine) thereby penalising all those sites that aren’t responsive.
