It
gets tedious fast, and you end up with stated widths in the CSS that
don??™t re?¬‚ ect the actual width of the divs. However, some designers
don??™t like the idea of the extra markup in their XHTML. If that??™s you,
with all these examples, you can if you want, remove the inner divs
(don??™t forget to remove their closing tag, too!) and move their associated
styles onto the main div??”from inner_nav to nav, for example.
If you do this, remember that you need to subtract the total width of
any left and right borders and padding from the stated width of the
div. Let??™s look at the CSS that relates to these inner divs.
Prevent Unwanted Over?¬‚ ow
I??™ve written a single rule for all the inner divs, using a group selector,
which hides the over?¬‚ ow of oversized content within them.
The CSS over?¬‚ ow property controls how elements deal with content
within them. The default setting, visible, causes the element to
expand to enclose the content within it. For example, if you add a
large image into the narrow nav column, that column would normally
expand vertically and horizontally to display the entire image.
Unexpected changes in column width like this are the curse of
?¬‚ oated layouts, as the rightmost column will move down under the
left column if the columns get pushed over to the right, and it suddenly
doesn??™t have room to sit where it belongs.
