Howto Improve

W3C/Web Accessibility Initiative
– w3.org/accessibility
The Web is fundamentally designed to work for
all  people, whatever their hardware, software,
language, culture, location, or physical or mental
ability. When the Web meets this goal, it is
accessible to people with a diverse range of
hearing, movement, sight, and cognitive ability.
Accessibility:
Make sure that People with disabilities
can effectively interact with the Web
– Aaron Gustafson (Foreword in: Sarah Horton. “A Web for Everyone.”)
“On the web, every decision I make can have a
profound effect on hundreds of thousands (if not
millions) of people’s lives. I can make checking into
a flight a breeze, or I can make it a living hell.
That’s a lot of power. And to quote Stan Lee: ‘With
great power comes great responsibility.’”
