What is Responsive Design?
Responsive web design (RWD) is a web design approach aimed at crafting sites to provide an optimal viewing experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from mobile phones to desktop computer monitors).
A responsive design simply means a website that has been constructed so that all of the content, images and structure of the site remains the same on any device. For example, when a user accesses a site on their desktop, they are getting the full view of the site. But when that same user goes to visit the site from their smartphone or tablet, the site will retract to fit on the smaller screen.
In other words, with a responsive website design, you don’t have to have worry about having different websites for various devices or making sure that your site runs properly on a mobile device.
