Using JS to position a div

I'm trying to position some divs absolutely (so they float)
and I want
them to appear at a fixed point on my page.  So, normally
I'd use the
whole {top: 100px; left: 100px;} type of set-up.  However,
the page is
centered.  So, depending on the width of the user's browser
(or screen
resolution etc...) that defined point in space doesn't
match up with
where I want it to be.

Is there an easy way to either:

a)define a 0,0 point... or
b)figure out where one point is and position my div
accordingly?

Thanks,
Bryan

Assuming you know the width in pixels of your page, it
shouldn't be too
bad. Use the innerWidth of the window to figure out how wide
the whole
thing is in pixels, then subtract the width you know you're
using, and
you know how much extra there is, making the X-offset you
need 1/2
that.

scrollTop should give you the current top, so using the two,
you should
be able to nail it.

Hope that helps,
~A!
