I'm playing around with an idea: http://www.harveypooka.net/mountain/index.html Now, you see the tree line at the bottom of the page, I want that to always stay with the viewport. So, if the user scrolls, the treeline stays at the bottom. At the moment it works if you resize the window, but not if the content continues past the bottom of window and the user needs to scroll; the treeline stays where it is. I've gotten in a bit of tizz about positioning. I'm sure this is dog simple. Help?
