Frames: Just Say No.
Navigation does not work with frames since the
unit of navigation is different from the unit of view. If users
create a bookmark in their browser they may not get the same view
back when they follow the bookmark at a later date since the bookmark
doesn't include a representation of the state of the frames on the
page.
Even worse, URLs stop working: the addressing
information shown at the top of the browser no longer constitutes
a complete specification of the information shown in the window.
If an author copies the URL in order to include it as a hypertext
anchor in one of his or her own pages then that anchor will not
lead readers to the desired view but to the initial state of the
frameset. Similarly, if a user decides to send an email message
to a friend with the recommendation to check out a page, then copying
the URL from the browser will not work if frames are used since
the URL points to the frameset and not to the current view (with
the information of interest to the friend). Given that social filtering
is one of the most powerful mechanisms for information discovery
on the Internet, it is an utter disaster to disable the URL as an
addressing mechanism.
Print Problems
Many browsers cannot print framed pages appropriately.
Of course, most browsers don't print anything really well, but at
least regular pages normally print in full. With frames, it is common
to have the print command result in the printing of a single frame.
Printing the full page is difficult with scrolling frames: should
only the visible part of the frame be printed or should the content
be allowed to expand and take up more room than it does on the screen?
Search Problems
Search engines have trouble with frames since
they don't know what composites of frames to include as navigation
units in their index. They usually index the Meta Tags or Keywords
that are on the frameset, ignoring all other pages in your site.
Some of them, such as Lycos' spider, summarise Web pages with "this
site uses frames but your browser doesn't support them" error
messages. Your site is literally invisible to search engines.
User Preferences
Many websites that offer users a choice between
regular and framed versions have found that most users prefer frame-free
designs.
