The following is a summary of currently available functionality:

Page structure

• Unique, descriptive page titles are present on every page
• Logical heading structure is used – all pages have unique heading 1 followed by descriptive heading 2 and so on
• Lists are used where possible (e.g. navigation)
• Tables are used for tabular data only, tags used for header rows and header columns
• The reading and navigation order is logical and intuitive
• Instructions do not rely on shape, size, colour, sound, etc.
• Skip to content link(s) are present
• Text is re-sizable without loss of content (text reflows)

Colour contrast

• Colour alone is not used to convey content (e.g. colour coding)
• Colour contrast ratio (foreground vs. background) is at least 4.5:1

Images

• All images have a valid alt attribute (decorative images have alt value of null)
• Linked images have an alt attribute that describes the destination page
• Button images have an alt attribute that describes the function of the button

Audio and video

• Subtitles and transcript/descriptive text is provided for audio/video *
• Audio description is provided for video *
• Audio can be stopped, paused and muted
• All controls are accessible via keyboard

Moving Content

• The user can switch off any time-limits
• Automatically moving, scrolling or updating content can be paused, stopped or hidden by the user
• No content flashes more than 3 times per second

Forms

• Buttons have descriptive values
• All form fields have associated text labels
• Related form elements are grouped with field set/legend
• All form labels are unique and informative
• The form label provides instructions e.g. if required, minimum length, etc.
• Form error/validation messages are clear and intuitive, providing instructions and suggestions

Links

• Link text is unique and makes sense out of context
• Multiple ways to navigate through the site - navigation, sitemap, crumb trail, search, etc.
• Links are distinguished from surrounding text - e.g. underlined, bold, etc.
• Highlighted state of links - active, hover, focus

Keyboard access

• All functionality is available via keyboard - e.g. forms, tabbing through the links, etc.
• Access keys / keyboard shortcuts are better avoided (due to compatibility issues)
• Keyboard focus is never locked or trapped
• It is visually apparent which element has the current keyboard focus

Predictable

• No unexpected changes to the page, e.g. on focus or interactions or auto-updates
• Consistent elements throughout sites, e.g. navigation, search boxes, general layout etc.

Mark-up

• Lang attribute is set
• Page content in a different language is identified
• Significant HTML validation/parsing errors are avoided
• Mark-up facilitates accessibility including HTML specifications and using forms, form labels, frame titles, etc. appropriately. Use of WAI-ARIA for dynamic content changes, roles and keyboard access
