Okay, let’s see if I can explain what I mean, here’s an image to help:

So as you can see in the image, I need to get the green arrow from its current location to being placed outside the main div that holds it. I need so if the page is re-sized the arrow will stay in its position.
If you need any more information, please let me know. Sorry if this is too vague, I wasn’t sure how to explain it.
Thanks!
Give the container element
position: relative;and then give the arrowposition: absolute; top: 0; right: -x;(where x is the width of the arrow).Here is an example: http://jsfiddle.net/joshnh/xpFPd/
