JS Float Pusher - Sand Bagging Tutorial
How do you get a float to remain aligned to the bottom of a container regardless of the containers height? You use javascript that's how! Little or a lot of content, large or small height on the container, no problem! As long as JS is enabled, the float is glued to the bottom of the container. It's a very cool script!
