You can test if a website is responsive by resizing the browser window with the mouse if you're using a laptop or desktop device. If you're on your phone...Ba dum tss!!

Its remarkable how fast mobile devices have become popular. In 2014 StatsCounter Global Stats reported Mobile internet usage soars by 67%, and the average American owns 4 devices. Over the past few years responsive web design (RWD) has become more, and more prevalent partly because the number of mobile devices has risen dramatically. Mobile devices now consume over 50% of the Internet usage.

Most business websites that have been developed in the past 3 years are likely responsive. Typically this means the content 'responds' to the device. This seems to be the standard default approach for most websites - re-arrange and re-size the content to fit the screen.

The elements just stack up, one on top of the other. All the content is there. No pinching to zoom in, no turning your phone the other way around for a better view. The content is the same on any device you're using. But is it the content that you are looking for?
