Accessibility has been the subject of standardisation proposals by the
W3C, the authoritative body controlling WWW standards. Their guidelines
and implementation recommendations offer a clear and straightforward way
to implement the evolving standards.
HTML language features affecting
usability are prioritised into three sets of checkpoints with graded
priority. Priority 1 checkpoints seriously affect usability, priority 2
checkpoints make it difficult for one or more groups and priority 3
checkpoints make it somewhat difficult for one or more groups. As far as
is practicable we build to these standards and as a minimum would expect
to implement all priority 1 checkpoints.
Meeting standards isn't enough - Conformance to these standards can
easily be verified by web sites such as Bobby, but this by no means
guarantees an accessible, easy to use web site, as visits to many Bobby
approved sites will demonstrate.
As with any web
site, clarity and ease of use stem from the way in which the
content is divided into sections and presented to the user. If the
information is organised in a clear and logical way, then applying the WAI
guidelines should result in a thoroughly accessible site.
