CLF for the Internet - Navigation and Format![,](/web/20060117055310im_/http://www.tbs-sct.gc.ca/cioscripts/images/line450x1.gif)
Frames must only be used on GoC
sites as an alternative format.
Rationale
Frames are an example of non-sequential text, which can create interpretation
problems for individuals using assistive technologies and for advanced multi-modal
systems. Frames present additional problems when trying to ensure that organizational
identification and CLF elements
remain attached to content when located via search engines. Frames can also prevent
users from easily bookmarking specific Web site content.
Interpretation
It is the responsibility of individual Web developers to ensure Web sites are
accessible to all citizens.
Web page layout is critical to universal accessibility in that some common styles
of Web page design actually create barriers for individuals using assistive devices
and non-graphical technologies. Such techniques can only be used as an alternative,
where universal accessibility has been otherwise guaranteed.
