The main problem with
this type of layout is that an absolutely positioned element is removed from the
document flow, and doesn??™t affect subsequent elements at all. A multi-column,
absolutely positioned layout, in which any column can be the longest, makes it
virtually impossible to display a footer at the bottom of the rendered document.
You can use the following checklist as a rough guide when deciding which type of
layout to use for a multi-column document in which any column can be the longest:
?– If the source order is important, and it??™s different from the presentational order,
and you don??™t need a footer on the document, use absolute positioning.
?– If you need a footer, use floats. Source order can be maintained with the help of
negative margins and relative positioning, if necessary, albeit with a lot of extra
work for IE??”especially if the page width is variable.
A third option is to use the table-related values for the display property, but,
unfortunately, lack of support by Internet Explorer hinders the use of those values
for any general-audience site at this time.
