Web Content Accessibility Guidelines Flashcards

A development team is building a complex data visualization component. They ensure it can be fully operated via the keyboard and that all information conveyed with color is also available in text. However, they are concerned that the complexity of the data might be difficult for some users to interpret. Which WCAG principle is MOST at risk of not being met?

Answer: Understandable

The principle of 'Understandable' states that information and the operation of the user interface must be understandable. While the component may be perceivable (available to senses) and operable (keyboard accessible), the concern that the *complexity* of the data may be difficult to interpret directly relates to whether users can comprehend the information being presented.

Which of the following statements most accurately describes the relationship between WCAG conformance levels A, AA, and AAA?

Answer: To conform to Level AA, a webpage must meet all Level A and Level AA success criteria.

WCAG conformance levels are cumulative. To achieve a certain level, you must satisfy all the success criteria for that level and all levels below it. Therefore, to meet Level AA, all Level A and Level AA criteria must be met. Level AAA is the highest level, and most legislation points to Level AA as the target, not AAA.

A website for a government agency provides critical information to the public. The agency wants to ensure the highest level of accessibility possible, but its web team advises that achieving full WCAG Level AAA conformance for all content is not always feasible. Why is Level AAA often considered a target for enhancement rather than a strict requirement for all content?

Answer: It is not always possible to satisfy all Level AAA success criteria for certain types of content and contexts.

The W3C, which develops WCAG, acknowledges that it's not always possible to satisfy all Level AAA success criteria for all types of content. For this reason, Level AAA is often not required by general policies but serves as a best practice to make content as accessible as possible. The other options are incorrect; AAA is not being deprecated, applies to all web content, and provides benefits beyond A and AA.

WCAG 2.2 introduced several new success criteria to address modern web challenges. One of these, Success Criterion 2.5.7 Dragging Movements, was added primarily to benefit users with which type of disability?

Answer: Motor disabilities

Success Criterion 2.5.7 Dragging Movements requires that any functionality using a dragging motion can be operated by a single pointer without dragging. This directly benefits users with motor disabilities who may struggle with the precision and sustained action required for dragging and dropping.

An e-commerce site is undergoing an accessibility audit. The auditor notes that on the multi-page checkout process, the user is required to re-enter their billing address after they have already entered an identical shipping address. This issue would be a failure of which new success criterion in WCAG 2.2?

Answer: 3.3.7 Redundant Entry

WCAG 2.2 Success Criterion 3.3.7 Redundant Entry is designed to help users, particularly those with cognitive or memory-related disabilities, by ensuring that information already entered by the user is made available to them instead of requiring them to re-enter it. Requiring the user to type the same address twice in one process is a direct violation of this criterion.

The 'Robust' principle in WCAG is intended to ensure content can be interpreted reliably by a wide variety of user agents. Which of the following is the BEST example of a failure to meet the Robust principle?

Answer: A website that uses custom JavaScript that only works in the latest version of one specific browser.

The Robust principle states that content must be robust enough to be interpreted by a wide variety of user agents, including assistive technologies. Content that relies on a single, specific browser version is not robust because it will fail for users of other browsers, older browsers, or various assistive technologies. The other options are failures of Perceivable (captions, contrast) or Operable (time limit).
