Web Design in a Nutshell, 3rd Edition

Width and margins

Although not strictly necessary, you may want to get rid of multicolumn formatting (if there is any) and display the content in one column that fills the available width of the page. Changing the position of positioned elements to static and changing the float for floated elements to none should take care of undoing the columns. Setting the width of all elements to auto is the best approach for making sure they’ll occupy the full width of the page after margins are applied (either by the browser or in the style sheet).

Warning

If your web page uses floats for long elements, make sure that the print style sheet resets the float to none. There is a bug in Gecko-based browsers that causes long floats to get clipped after the second or third page. Setting float: none for long elements fixes this problem.
