Accessibility based on WCAG 2.1
Web Content Accessibility Guidelines (WCAG) 2.1 covers a wide range of recommendations for making web content more accessible.
According to the W3C, content on a web page or web applications (including text, images, forms and sounds) should be:
- Perceivable: usable regardless of a person’s ability to see, hear or touch.
- Operable: usable forms, controls and navigation.
- Understandable: content and interface are clear and easy to understand.
- Robust: content can be used reliably by a wide range of devices.
It is important that accessibility is an on-going commitment. While a site may comply with WCAG 2.1 at its launch, those standards also need to be maintained as new content and features are added.
Factors that help improve accessibility include:
- Using clear labels for navigation and important buttons.
- Using clear and simple language.
- Ensuring that information does not rely solely on colour.
- Providing accessible documents.
- Providing Alternative (Alt) Text, transcripts or captions for video and audio content. A good summary may be provided to identify what the video/audio is about.
- Provide information in alternate formats to make it more accessible to a diverse range of people. See Written Text Guidance, Alternate formats.
- Evaluating the accessibility of a website. When developing or redesigning a site, evaluating accessibility early and during the development process can identify accessibility problems when it is easier to address them.
