Gates for every traveler
Some visitors can't see the screen, and some can't use a mouse. A good site works for them too.
Web accessibility means building sites that everyone can use: including people who are blind, deaf, have low vision, can't use a mouse, or find complex text hard.
It's often written a11y: an a, then 11 letters, then a y.
Many people use assistive technology to reach the web. These tools read the code behind your page, so your HTML decides whether they can make sense of it.
- Screen reader: reads the page aloud: NVDA (free) and JAWS on Windows, VoiceOver built into Apple devices, TalkBack on Android.
- Keyboard only: Tab and arrow keys instead of a mouse.
- Screen magnifier: zooms in on part of the screen.
- Voice control: clicks and types by speaking.
