Responsive WordPress themes are those themes which are built to be fluid and flexible enough to fit in any display size. Their ability to adapt to all types of displays of various devices makes them quite desirable as they provide people viewing a website from tablets and smartphones a beautiful and proper view of it. Website owners prefer these themes, considering the growing number of people connecting to the internet from various tablets and smartphones. Before the advent of these responsive themes, dedicated WordPress mobile themes were used for this purpose.
