Question

I was just thinking, and thought it would be cool if there was some trick to make it seem like when the user clicks on a new page, like on the main menubar that is identical across the site, if there could be a seamless transition that gives the illusion that the data changes but they haven’t gone anywhere, even though they are really now on an entirely new web page.

Answer 1

The proper way to do that these days is to not load an entirely new web page (if that kind of experience is your goal).

The easiest way to do so is jquery.load:
