The phenomenon of parallax scrolling website design (Parallax Web Design) is growing in popularity across the internet, bringing the user experience to a new interactive level of online viewing. With web designers and developers constantly exploring new ways to make their web presence more appealing to their sites visitors through engaging visuals and functionality, parallax scrolling has taken hold.
The term parallax first came from the visual effect of 2D side scrolling videogames that used different background image movement speeds to create the illusion of depth during gameplay. This was generally done by making the background of the game move slower than the foreground in order to make it seem further away. This same concept applies to parallax site design in which the background of the website moves at a different speed as the rest of the page for an impressive visual effect that allows for countless creative applications for online storytelling.
