Making a site usable by everyone.
THE DEFINITION
A site people can use regardless of how they access it: with a screen reader, by keyboard alone, with low vision, with limited motor control, or with a cognitive difficulty.
WHO THIS AFFECTS
People who are blind or have low vision People who are deaf or hard of hearing People with motor impairments who cannot use a mouse People with cognitive or learning difficulties Older people, whose vision and dexterity change Anyone on a small screen, in bright sunlight, or with a broken mouse
THAT LAST GROUP
Accessibility measures help far more people than the ones they were designed for.
Good contrast helps everyone reading outdoors. Clear structure helps everyone scanning.
WHAT IT IS NOT
A separate version of your site for disabled people. That approach is outdated and produces a worse experience.
It is the same site, built so it works.
THE COMMERCIAL CASE
People with impairments are customers. A site they cannot use is a customer you cannot serve.
THE HONEST CASE
Do it because people need it. The other benefits follow.
