The document discusses lessons learned in making content management frameworks and developer tools more accessible. It notes that while basic accessibility features like headings and form labels are often supported out of the box, richer interactive elements like dynamic forms, search autocomplete, and charts present greater challenges. It recommends planning accessibility into frameworks by listing all major features, describing how they should work, prioritizing keyboard support, choosing tools with active communities, doing quick accessibility checks, and leveraging forums and examples.

2. CHALLENGE
Costly commercial software
• As the market crashed in the late 1990s and early
2000s and the recession hit, agencies and
businesses were finding ways to cut costs.

8. Content Management
Publish, Edit, Approve
• WordPress, Drupal, Joomla, Grav, SharePoint and
other content management tools let organizations
build websites quickly and manage content easily.
The built-in options out of box for most of them
include the ability to tag content with headings, used
by assistive technologies.
• Content owners can also insert media, and in some
better designed tools like WordPress, add alternative
text.

9. Navigation
Drop-downs, Megamenus, Mobile menus
• Menu trends totally collapsed menus and that
drop-down menus that are only available on hover

10. Forms
Cues, Formats, Feedback
• You can also quickly stand up forms to collect
information such as Contact Us, newsletter
subscription, registration, or application
information using Drupal’s Ctools and various
frameworks and plug-ins, like Contact Form 7.
• Many offer support to let you include required
indicators, date picker widgets, and informative
text near the fields to help users know what
format is needed.

11. Dynamic Areas
Autocompletes, Data-dependent forms, Pop-ups
• Functionality like autocomplete, typeahead search
/ results, data-driven forms are popping up across
sites.
Creative Commons – Some Rights Reserved
11

12. Dynamic Sidebars
Feedback, Chat, and Support
• More sites are including feedback and chat options
off to the side. In some cases they pop up without
any user interaction, which can cause confusion for
users.

15. Big Data
Charts and Tables
New and easier to leverage chart libraries are giving
organizations quick and easy ways to show big data in
charts and scorecards.

17. FOR FRAMEWORKS
Accessible content’s easy(er)…
• Content headings
• Labels for basic fields
• Table headings
• Skip to main content
Creative Commons – Some Rights Reserved
17

18. WHEN USING FRAMEWORKS
Richer content and interactions fell short
1. Title, not alt attribute, was
default text for media
2. Tables pasted in from Word lost
headings
3. Keyboard and speech recognition
had less support
4. Accessible rich Internet
application (ARIA) support to
provide context, info varied –
good for menus, but lacking for
autocomplete and dynamic
widgets

19. DEMO
Pop-ups, menus weren’t reachable
• Websites with pop-ups for tooltips, navigation
menus, and modals and dialogs weren’t always
reachable by keyboard.
Creative Commons – Some Rights Reserved
19

20. LESSONS LEARNED
Add key listeners, focus management
• Add keyboard alternative for click and hover events
– Use native <a href> and interactive elements (button, etc.) when possible
– Level 1 menu links sometimes removed href that provides keyboard
support
– Add hover only after keyboard handled
• Verify that focus outline available
• Set focus when open pop-up
windows and dialogs
• Provide a11y info via Help,
offscreen text, or ARIA

21. DEMO
Form labels, helper text, feedback weren’t accessible
Example: https://kwalser.wufoo.com/forms/applicant/

21

22. LESSONS LEARNED
Adjust rendering of labels, helper text with ARIA, listeners
• Adjust out of box required field settings
– Change * to Required
– Add required attribute to field
• Assign field descriptions to fields
• Adjust code for custom items
– Forms in dialogs
– Character counts

23. LESSONS LEARNED
Set focus to feedback and add “aria-describedby”
• Improve status messages
– Move focus to success / error messages after validation
– Include links to fields with problems
• Associate error message with field via ARIA

24. DEMO
Search, typeahead weren’t keyboard accessible or
didn’t announce result set

24
Example: https://www.nps.gov , https://www.cdc.gov

25. • Where input fields offer
typeahead functionality, use
ARIA and event listeners if
needed to enable focus to
move to the list as soon as
it’s available.
• Include the empty div /
container in the code on
page load and position it
immediately after the
search box to minimize
extra work.
Creative Commons – Some Rights Reserved
25
LESSONS LEARNED
Test with keyboard and check ARIA attributes
Sample Code
<input id="search-input" name=" search-input " type="text" class="form-
text" size="60" maxlength="128" aria-haspopup="true" aria-
autocomplete="both" role="combobox" aria-describedby="number-results">
<p class="show-on-results sr-only" id="number-results">10 matching
results</p>
<ul class="show-on-results" id="search-results" role="">
<li><a href="…">medicaid</a></li></ul>

26. LESSONS LEARNED
Extend typeahead functionality
• Add offscreen element (e.g., <span>) with
role=“status” and aria-live=“polite” to provide
feedback on # of results, navigation tips
• Add keydown listener on down arrow to show and
set focus on the first result

27. DEMO
Table abilities, plugins varied in accessibility27

28. LESSONS LEARNED
Pick accessible libraries and tweak as needed
• Change filter option labels to
“Filter” to avoid Search hot
command collision in speech
recognition
• Set focus back to logical spot when
pager links used
– Previous, page #, and next caused page
refresh, focus set to top rather than
search results (or pager links)
• Associate text and map results for
location-aware searches (e.g., Near
you) to improve map a11y

32. A better strategy
» Planning A11y into Frameworks
32

33. 1. List all major features
• Navigation
– Drop-downs, Jump links, Into / out of dialogs and auto-complete
• Search, faceted drill-down
– Results, Filtering, Pagination / pager links, Table headings
• Sliders, carousels, galleries, tabs
• Content sharing options, plugins
• Maps and data charts
Creative Commons – Some Rights Reserved
33

34. 2. Describe interactions, test criteria, examples
• If click triggers action,
keyboard will also…
• If hover triggers action,
keyboard alternative…
• If error returned…
• If many links / elements in
the widget...

34

35. 3. Prioritize keyboard access
• Start with click and key event listeners
• Only use mouse-related listeners for non-critical
interactions
• Try interacting from different devices
– Keyboard only
– Mobile

35

36. 4. Choose tools with large communities
• Look at downloads, usage, active maintenance
• Find resources on StackOverflow, Quora, JSFiddle.net, CodePen.io
– site:codepen.io +aria +example +jquery/drupal/wp
– site:jsfiddle.net +aria +example +jquery/drupal/wp
– site:jsbin.com +aria +example +jquery/drupal/wp
• Google site:frameworkname +accessibility +…
– “How do I”
– Keyboard access

37. WordPress Accessibility Site

• WordPress’s accessibility site includes resources for
creating accessible plugins and themes.

38. Drupal Groups Site
Accessibility (AX) Pledge Modules / Themes
• Drupal Group’s site lists modules and themes that
have pledge to be accessible and those that the
community wishes would take the pledge.

Drupal has made a pledge to accessibility, to make both its core framework
accessible and challenge module and theme developers to take an accessibility
pledge. This means they will “try” to make their products accessible.
Accessibility pledge modules/themes

39. Check usage stats if available

40. 5. Do a quick check
• Can you navigate using the keyboard? (Tab key)
• Are any menus keyboard-accessible, either with Enter or
Spacebar key on parent? Can you reach any pop-ups?
• Do form elements wrap labels in <label> tags?
• Do any dynamic elements have aria-* attributes in the
code?
• Do dynamic elements that return information or results
relate the element with the results?

41. 6. Use forums, API, examples
• Many JavaScript libraries document their APIs and
options
• Look for examples to see if and how you can
change things like labels, event listeners, and other
options
• Check forums like StackOverflow and others to see
if others experienced same issue
Creative Commons – Some Rights Reserved
41

42. • Look for accessibility frameworks that extend the
functionality or provide examples of how to make it
accessible

45. Summary
• Rich, interactive elements present greatest challenge
• “Quick check” of plugin, module, library accessibility helps
• Describe how interactions should work and find examples
