[Javascript] stationary buttons

[Mike Dougherty]

Didn't you find this effect annoying with ads?  I personally would
prefer to not have some artificial navigation control covering the
content I'm trying to read.  If I figured out a way to scroll the page
down, It's pretty likely that I have a way to scroll it back up.  The
floating button trick might have been useful before the mouse's scroll
wheel (or similar control) but it often appears more klunky than
necessary.  

If your pages are so long that one or two flicks with a scroll wheel
don't get you where you want to be, then the page is probably just too
long to keep anyone's attention regardless of the controls you provide.

My $0.02 is that a web developer should provide the cleanest-looking and
most efficient working solution... let the sales and marketing people be
responsible for making the site's content ugly <g>

I am looking for some help in finding how to create a button (most
probably in a layer, I guess) that will remain stationary in position on
a page as the page scrolls down, so that it never moves out of sight
along with the other elements on the page. I have seen this effect
somewhere recently with ads, but have not been able to find it since.
