The keyword "Responsive Web Design" means websites that are displayed clearly and attractively on every medium. At LeanPort, for example, we know that the majority of our customers' websites are now visited from a tablet or smartphone. The sizes of the screens vary and our job is to deliver an equally compelling website experience on all devices.
The term "responsive" already includes the procedure. Translated into German this means something like "reacting". It reacts to the screen size and the browser used.
