Responsive design is a new way of building WordPress sites so the pages change size and shape according to the device they’re viewed on.
It’s an all-in-one solution for your website. There’s no need to have a separate site for cell phones – responsive design figures out exactly what kind of phone or tablet or desktop computer your visitor has, then delivers the layout that works best.
The cell phone version is not just a tiny version of the same site you see on your desktop. Responsive design automatically makes a large and readable version of your web pages shaped to fit your visitor’s phone.
