11 Steps to Accessibility

  1. Provide alt-text -- you can even set as decorative
  2. Label your form elements -- can use aria-label
  3. Add closed caption for video, audio description for animations -- training materials need the close captioning https://vimeo.zendesk.com/hc/en-us/articles/224968828-Captions-and-subtitles -- Amazoon has tools
  4. Be sure your contrast ratio meets minimum thresholds -- 4.5:1 for text, 3:1 for others
  5. Make all link text descriptive and underline them -- "click here" or "read more" VS 'folow this link to "Wikipedia"'
  6. The color of any given content cannot be the only indication of meaning -- "required fields are in red" VS required are in red and marked with * --
  7. Make sure your font size is at least 16px and is still properly spaced when enlarged to 200% -- plugin to see https://www.stpetedesign.com/ada-section-508-compliant/
  8. Error handling - 'Errors' vs 'Title is Required' and 'Last Name Required'
  9. Tab navigation - entire site should be keyboard navigable -- take your mouse and put it in the drawer majority of suits brought because couldn't interact with site functions -- make sure focus state CSS is clear
  10. You must offer flexible time limits (if any) associated with the website or software -- think about the time it takes for a screen reader to finish page
  11. provide skip navigation links so that users can skip repetitive content such as nav menus, widgets etc -- Mega Menus work terrible for screen readers -- primary content link only shows when tabbed into -- Add Skiplinks with wp-accessibility, skiplinks don't have to always be visible
