At minimum, every page in a WWW site should have a link to its home page, or
at least to a submenu within the site. Button bars are used to place fixed
links between a series of pages to bind them into a document. Beware of
using icons in place of text buttons, as they are seldom unambiguous. If
icons are used they should also have a text option in case users have turned
off their graphics to speed up access
"If your users are required to memorize a unique set of symbols just to move
around your Web site, they probably won't stick around for long."
Exercise
- Find 3 sites with useful buttons or other navigational aids and
download them to try them out on your own home pages (tip: there are several
sites that specialise in shareware buttons, backgrounds an other useful
graphics files and software)
