Accessibility introduction¶
The Web Accessibility feature helps you make your website compliant with WCAG 2.0, 2.1 & 2.2 A, AA, and AAA guidelines.
Web accessibility is the concept that websites and website content must be accessible to anyone, regardless of how they use the internet. Websites must give a way for people with disabilities such as visual, auditory, physical, speech, cognitive, language, learning, and neurological to access the information. Some examples of other ways to use the internet are:
- Screen readers
- Adaptive technology (such as eye-tracking)
- Audio-based such as verbal transcripts
- Subtitles for audio content.
Compliance is shown for the following:
Page compliance = percentage of checks that the page is compliant in.
Domain compliance = Average page compliance in this domain.
The four principles of web accessibility for website content as specified in W3C are:
From: Understanding the four principles of Accessibility: "Perceivable - Information and user interface components must be presentable to users in ways they can perceive. This means that users must be able to perceive the information being presented (it can't be invisible to all of their senses). Operable - User interface components and navigation must be operable. This means that users must be able to operate the interface (the interface cannot require interaction that a user cannot perform). Understandable - Information and the operation of the user interface must be understandable. This means that users must be able to understand the information as well as the operation of the user interface (the content or operation cannot be beyond their understanding). Robust - Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies. This means that users must be able to access the content as technologies advance (as technologies and user agents evolve, the content should remain accessible).
If any of these are not true, users with disabilities will not be able to use the Web.” |
This tool gives suggestions and tips on how you can make your website better for visitors with a disability by improving their ability to perceive, understand, contribute, navigate, and interact with it.
