Responsive web design (RWD) is an approach to web design aimed at creating sites that provide an optimal viewing and interaction experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from desktop computer monitors to mobile phones)
Responsive web design is becoming more important as the amount of mobile traffic now accounts for more than half of total internet traffic. This trend is so prevalent that Google has begun to boost the ratings of sites that are mobile friendly if the search was made from a mobile device. This has the net effect of penalizing sites that are not mobile friendly.
To check whether a site is responsive, either view it on a mobile device, or size the browser window down to a few inches in width, and see what happens to the titles, text and images.
