Parallax scrolling has been around for some time and capitalizes on a 3D-like experience in a 2D environment. This special visual technique simply scrolls the background image at a slower rate than the foreground image or text, creating a sensation of depth or an almost 3D feeling. The bottom line is that you can create some pretty dynamic and interesting visual experiences for a visitor scrolling through your site.
Some website design trends come and go, but as we grow deeper into this scrolling culture, you may want to take advantage of the need for scrolling. Especially as mobile website usage increases, one thing is clear - we like scrolling on our phones. Even the split moment Instagram accidentally released a tapping to advance feed, the immediate uproar was enough for them to ditch the idea, at least for now.
