What is Responsive Web Design?
The responsive web design approach aims to create websites that offer optimal user experience across various devices and screen resolutions including desktop computers, tablets such as iPad, smartphones and other mobile devices. A responsive WordPress design smoothly adjusts its layout based on the screen size and resolution.
Responsive design offers better readability and usability on smaller screens such as smart phones. It also prevents you from creating a device specific mobile version.
A growing number of people are accessing internet through tablets and smartphones. This is why we are seeing an increase in the number of responsive themes that are being created by WordPress theme companies. If a large proportion of your website visitors are visiting your website using a mobile device, then you should seriously consider offering a mobile version or switching to a responsive WordPress design.
