Basics
Title
If possible, each screen should be supplied with a unique title and provided with headings that identify sections in the information hierarchy.
When people arrive on a screen, the title is the first piece of information they receive from assistive technology. To help people understand the product’s structure, unique titles should be created for each screen that briefly describes its contents or purpose.
Plain text
The user interface should not prevent users from selecting plain text on the screen.
Many users rely on using selected text as input for text-to-speech (TTS) or for looking up translations.
Decorative Elements
Purely decorative images and other elements should be hidden from assistive technologies.
Making VoiceOver describe a purely decorative image and elements can waste time for users and add to their cognitive load without providing any benefit.
User abilities
Users should be able to:
zoom in up to 300% without problems
navigate most of the website using just a keyboard
navigate most of the website using speech recognition software
use most of the website using a screen reader (including the most recent versions of JAWS, NVDA, and VoiceOver)
