Perceivable

When a website’s information and components are designed to fit all users it is perceivable. This can be done in many ways text alternatives, time-based media, adaptability, and distinguishability.

 

Text alternative:

  • Allowing all texts to be changed into large print, speech, symbols, easier language, and braille.

 

Time-based media:

  • Having both audio-only and video-only options
  • Offering pre-recorded captions
  • Displaying audio descriptions or closed captions
  • Showing live captions that are synchronized with the media
  • Option for pre-recorded sign language
  • Provide extended audio descriptions with all videos and clips

 

Adaptable elements:

  • Using landmarks to identify regions of the page
  • Providing information with easy access (ex: banners, landmarks, tabs, etc.)
  • Allowing for both portrait and landscape views
  • Providing instructions to operating elements for easy understanding
  • Having a proper reading sequence
  • Providing textual identification for all items

 

Distinguishable components:

  • Using different colors to distinguish separate groups of information
  • Allowing the user to control any audio played on site
  • Having a contrast ratio of at least 4:5:1
  • Option to resize text
  • Providing information on the images shown
  • Having a contrast ratio of at least 7:1
  • Using text spacing
  • Always having the hover visible

 

Operable

A website is completely operable when all users can navigate the components. It’s important to make your website functional through various inputs beyond just a keyboard.

 

Keyboard accessibility:

  • Proving keyboard handling functions to get around specific time strokes and specific movements.
  • Making sure users can exit information in multiple ways and not just via keyboard.
  • Allowing users to turn off single-key shortcuts

 

Enough time:

  • Allow for time adjusting (turn off, adjust, and extend time limits)
  • Allow for pausing, stopping, and hiding videos
  • Minimize interruptions
  • Allowing the user to continue an activity without losing data after re-authentication
  • Provide a warning of the time limit of each activity

 

Seizures and Physical Reactions:

  • Don’t allow components to flash up on the screen more than three times
  • Allowing motion animations to be disabled

 

Navigable:

  • Adding links to different parts of your webpage to make navigation easier
  • Having all page’s titles with a description or purpose
  • Allowing for multiple ways to access each part of your page
  • Label all headings
  • Putting all information in an easy-to-understand location
  • Making sure the keyboard focus indicator is visible

 

Input Modalities:

  • multipoint or path-based gestures for operation on a single pointer
  • Ensuring drag-drop actions can be removed
  • Providing labels with text for all images of text or text alone
  • Having the target for pointer inputs is at least 44 by 44 CSS pixels
  • Making sure your content does not restrict various input mechanisms

 

Understandable

It’s important to make sure all text is readable and easy to understand

 

Readable:

  • Allowing HTML element for all language components on a page
  • Providing a definition for uncommon/unusual words
  • Having all expanded forms or meanings for abbreviations
  • Providing text summary with lower secondary education
  • Providing a glossary

 

Predictable:

  • Limiting or eliminating new windows opening
  • Providing submit buttons and informing the user what is happening
  • Making sure all repeated components are shown in the same order each time
  • Providing consistent identification for content such as labels and names
  • Always giving the option to update rather than automatically updating

 

Input assistance:

  • Providing descriptions to identify the areas that were not complete
  • Allowing users to review and correct answers before submitting
  • Providing a checkbox before submitting
  • Providing a help link on your website
  • Providing frequently answered questions page

 

Robust

The website content must be robust for different assistive technologies to interpret it

 

Compatible:

  • Validate all web pages and links
  • Always include a name, role, and value for all interface components.
  • Providing a status message for assistive technology
