Drupal Accessibility
This section highlights ways to improve accessibility in Drupal.
Perceivable
1.1 Non-text content
Images have a text alternative.
How does Drupal handle alt tags?
Form inputs have properly associated text labels.
Frames are titled.
Text transcript is included for all prerecorded audio or video.
Supplimental description for video with sound.
Level AA Supplimental descriptive audio for video with sound.
1.3 Page structure
Headings, lists, and special text are used appropriately.
The page order is clear and makes sense.
Operable
2.2 Moving content and time limits
Any page or application with a time limit, offers the user options to turn off, adjust, or extend that time limit.
Understandable
3.1 Languages
The language of the page is identified using the HTML lang attribute.
Level AA The language of page content that is in a different language is identified using the lang attribute.
3.2 Predictable site behavior
When an element received focus it doesn’t change the page in confusing ways.
Interacting with a control doesn’t change the page in unexpected ways without informing the user ahead of time.
Required form elements or specific format requirements are noted in the element’s label.
Level AA If an input error is detected (via client-side or server-side validation), provide suggestions for fixing the input.
Level AA If the user can change or delete legal, financial, or test data, the changes/deletions can be reversed, verified, or confirmed.
Robust
4.1 Maximize compatibility
HTML/XHTML validates without significant parsing errors.
