a11y: Accessibility

Accessibility (often abbreviated to A11y — as in "a" then 11 characters then "y") in Web development means enabling as many people as possible to use Web sites, even when those people's abilities are limited in some way.

For many people, technology makes things easier. For people with disabilities, technology makes things possible. Accessibility means developing content to be as accessible as possible no matter an individual's physical and cognitive abilities and no matter how they access the web.
