WCAG posts
Foundations: lists
A list is generally agreed to be a series of words or phrases that are grouped together for a reason. That reason might be to remember the items we want from the store, to share our top five favourite movies, or to write down the steps needed to complete a task.
Foundations: landmarks
Most websites have common areas of content like a header and footer, a main content area, and one or more navigation blocks. Sighted people can identify these areas based on the way they're styled and the content they contain, but people who are blind cannot do that quite as efficiently. Landmarks, like headings and lists, offer screen reader users a more comparable experience for identifying and navigating between different areas of content.
Foundations: session timeouts
Session timeouts are designed to protect privacy and security, but if they’re implemented incorrectly, they can prevent people from completing tasks on a website.
Foundations: headings
Well structured content helps everybody understand and navigate documents. When coded properly in the HTML, headings, lists, and landmarks help people who use screen readers (software that reads what’s on screen) both scan and navigate pages.
Foundations: colour and meaning
Colour is a valuable tool for communicating meaning. But if you can't see colour, then meaning is lost. Always plan to use colour to convey meaning in combination with another means of identification.
Foundations: colour contrast
Good contrast is about using colours that provide enough variation between the content and background. This is particularly important for people who have conditions that affect vision or colour perception, as well as people browsing on mobile in different light conditions.
Foundations: text descriptions
Text descriptions are primary content, and when images do not have a text description, anyone who cannot see the image will not know its purpose. This means people may be unable to access content or perform related tasks.
Foundations: animations and flashing content
Animation and movement can add to the visual appeal of content, but poorly designed animations can cause problems for many people unless they are implemented correctly.
Testing WCAG 2.1 Level AAA
In our second post on WCAG 2.1 Level AAA, we discuss how to test against various Level AAA success criteria. You can read about the benefits of Level AAA and when to consider including Level AAA Success Criteria in our first post, Understanding WCAG 2.1 Level AAA, and what to do with your test results in our third post, Triaging WCAG 2.1 Level AAA.
Understanding WCAG 2.1 Level AAA
In our first post about WCAG 2.1 Level AAA, we discuss why it is useful and when to consider including it. You can also read about how some Level AAA Success Criteria expand upon Level A and Level AA Success Criteria and how to test them in our second post, Testing WCAG 2.1 Level AAA, and what to do with your test results in our third post, Triaging WCAG 2.1 Level AAA.
