Responsive Design is the buzzword of the moment for websites that scale and degrade gracefully across a range of devices from desktop computers to tablets and smartphones.
My website is now responsive. I can’t claim any great technical credit for it though. I simply upgraded WordPress to the latest version 3.6 and derived a child theme from the new default ‘twentythirteen’ theme.
This seems to work OK and provides a good foundation for making my other websites responsive.
