In reference to web design and coding…
Parallax is a much more complicated, time consuming web technology, but has many advantages to it, such as easy navigation, less clutter on the screen, larger, full screen graphics, sliding pictures, moving text, and displaying and easy “one page scroll” effect, that would ensure that the reader saw all the important information, rather than allowing the viewer to navigate on his own. Parallax also gives the illusion that the images are moving at a different speed that the scrolling text.
Many corporations are using this new technology, such as Apple, Sprint, and even the Whitehouse to name a few.
If you are interested in developing a parallax website please budget for additional coding/programming hours involved. Generally it will take 3 times as long to develop a parallax CMS platform. Parallax sites can be static (no updates) and fully engaging (forums).
