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. 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.

10. Dynamic Areas
Autocompletes, Data-dependent forms, Pop-ups
› Functionality like autocomplete, typeahead search
/ results, data-driven forms are popping up across
sites.

15. It’s accessible if I can…
› Get there
› Know where I am
› Know what I can do

ACCESSIBLE APPS
Overarching Principles

16. FOR FRAMEWORKS
Accessible content’s easy(er)…
› Content headings
› Labels for basic fields
› Table headings
› Skip to main content

17. 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
› Lacking for autocomplete and dynamic
widgets

18. 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.

19. 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

20. DEMO
Form labels, helper text, feedback weren’t accessible
Example: https://kwalser.wufoo.com/forms/applicant/
Creative Commons – Some Rights Reserved
20

21. LESSONS LEARNED
Adjust rendering of labels, helper text with ARIA, listeners
› Adjust out of box required field settings
– Change the symbol * to the word Required
– Add required attribute to field
$form[$key]['#attributes']['required'] =
'required';
› Assign field descriptions to fields
– $form['account']['mail']['#attributes'] = array(
'disabled' => 'disabled',
'aria-describedby' => 'email-helptext');
› Adjust code for custom items
– aria-haspopup or aria-controls when forms
and other options open in dialogs
– aria-live for things like character counts
Creative Commons – Some Rights Reserved
21

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

23. DEMO
Search, typeahead weren’t keyboard accessible or
didn’t announce result set
Creative Commons – Some Rights Reserved
23
Example: https://www.nps.gov , https://www.cdc.gov

24. • 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.

LESSONS LEARNED
Test with keyboard and check ARIA attributes
Sample Code – USA.gov Code, but with *improvements*!
<input id="search-field-small" type="search" name="query" placeholder="Search All Government"
onfocus="this.placeholder = ''" class="text usagov-search-autocomplete ui-autocomplete-input"
autocomplete="off" aria-autocomplete="list" aria-haspopup="true" aria-describedby="number-
results">
<p id="number-results" role="status" aria-live="assertive" aria-relevant="additions"
class="ui-helper-hidden-accessible"
<ul class="show-on-results" id="search-results" role="">
<li><a href=“…”>benefits for kids under 18</a></li>
<li><a href="…">benefits for seniors in tennessee</a></li></ul>

25. 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

26. DEMO
Table abilities, plugins varied in accessibility26

27. 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

31. GROUP EXERCISE #1
» Triage your site
› Look at menus, tables, interactive sliders, carousels, media,
search
› Watch for contact, registration, application forms
› How would you describe the items to a user who couldn’t see
the screen?
› If you had to tell Siri what to do, what would you say?
31

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...
Creative Commons – Some Rights Reserved
34

35. 3. Envision rendered code and review API
› How should the final code look to be accessible?
– <label for=“fieldID”>…
<input id=”fieldID” type…>
› Check the API to see how to generate that code
› Read HTML4 vs. HTML5 differences
– HTML4: Structure assistive technologies (AT) liked
<h2>A Heading</h2><div><p>…</p></div>
– HTML5: Anything goes – can sometimes break / do strange things with AT
<a href=“…”>…<h2><div>…</div></h2></a>
› Create standards for developers
– Unique ID – no duplicate IDs in rendered code

35

36. … and model frameworks
› Check frameworks like Assets.CMS.gov for code
examples

Assets.CMS.go
v

37. 4. Prioritize elements with native interactions
› Start with native interactions
– <a href…>, <button>…
› Find libraries, frameworks that emphasize keyboard
accessibility
› Only use mouse-related listeners for non-critical
interactions
› Try interacting from different devices
– Keyboard only
– Mobile
Creative Commons – Some Rights Reserved
37

38. 5. Choose tools with large communities
› Look at downloads, usage, active maintenance
› Check keyboard listener options, ARIA
› 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

39. WordPress Accessibility Site
https://make.wordpress.org/accessibility/
› WordPress’s accessibility site includes resources for
creating accessible plugins and themes.

40. 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.
Creative Commons – Some Rights Reserved
40
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.

42. 6. Validate HTML and fix JavaScript errors
› HTML and JavaScript
errors:
– Break assistive technologies
– Cause unexpected and
“can’t reproduce” results
– Break event listeners
“downstream”
› Validate HTML using W3,
IDE, or other tools
› Use plugins and browser
console to catch JavaScript
errors
Creative Commons – Some Rights Reserved
42

43. 7. 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?
Creative Commons – Some Rights Reserved
43

44. 8. 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
44

45. › Look for accessibility frameworks that extend the
functionality or provide examples of how to make it
accessible
9. Apply (or create) a11y helpers

46. GROUP EXERCISE #2
» Go back to your site (or a site)
› How would you describe those items and test them?
› What would you want to add, look for to improve accessibility?
46

47. Useful a11y resources
