I have a website. I want a div to appear after a user scrolls down the page a certain number of pixels, and again disappear if he scrolls back up again. You can see a sample of this on the following website:
[url removed, login to view]
If you scroll down the page, in the bottom right corner a box slides in saying to follow them on google plus. I want to copy this. The div that appears should be floating in the bottom right corner exactly as it is here. And when you scroll back up it should disappear.
Along with your bid please explain the method you will use to accomplish this.
