Attached is an extract from a website. we would like to add "fixed floating" functionality to the mainBox3 DIV which is in the top RHS of the page.
It should behave like this...
[url removed, login to view]
We need someone to update the [url removed, login to view] page in the extract so that the mainBox3 DIV behaves in the same way as the fixed div in the JQuery example.
