You can easily see this in action by loading up a site on your computer, then “shrinking” the screen (width wise). As it shrinks, the content should re-position itself (if it’s responsive) to fit on the current window size. There are many frameworks out there to facilitate responsive design. For the test site below, I used bootstrap:
