3. "Web accessibility means that people with disabilities can
use the Web. More specifically, Web accessibility means that
people with disabilities can perceive, understand, navigate,
and interact with the Web, and that they can contribute to
the Web. Web accessibility also benefits others, including
older people with changing abilities due to ageing."

websites usable by people of all abilities and disabilities.
When sites are correctly designed, developed and edited,
all users can have equal access to information and
functionality."
