Use it for footers too. They don't float as such, but as you are building each page, just adjust your page length in the " page properties" and reposition (drag) the HTML box containing the footer, to the bottom of the page.
Tip: When you design your base page using this method, make sure you size the footer' html box to fit hard against left side of page. That way it's only a matter of sliding the box down the left edge when constructing a new page. Also, make sure after you have moved any elements (should only need to move footer), recheck your page width iin the properties. You could have slipped over a little and width will stay at the max width element caused during the move.
