    Accessibility Team Update: June 18, 2014 

    Visual Focus In Left Navigation

    Screenshot of admin left navigation showing Posts menu selected with New Post submenu selected

    Posts menu selected with indistinguishable darker black shading, Add New sub menu item selected with text in dark blue. Note that dark blue text against dark gray is hard to see.

    Color Alone

    Visual focus indicators for wayfinding are relied on heavily by some keyboard-only users. @helen notes the enhanced visual focus indicators now in trunk. Ticket #28267 needs a lot more work bringing the focus style to various places but one area that needs a smart solution is left navigation. Now we are relying on color changes which are, in some instances, too subtle. Indeed, color is not to be used as the only visual means of conveying information, indicating an action, prompting a response, or distinguishing a visual element.

    Suggestions

    We discussed this for most of the meeting and here are some suggestions.

    • Helen reports that a blue glow does not look good
    • White outline around menu item with white outline also around selected submenu item
    • Reversing the colors with another undefined indicator element
    • Triangle to the left of main menu item and selected submenu item
    • Underline under main menu item and selected submenu item (might be mistaken for links)

    Solution Needed

    We need some suggestions for an elegant solution. Bear in mind that there are eight admin color schemes and any solution should take that into account. I have created ticket #28599 to work on this issue. A WordPress Accessibility Team shirt to the person who comes up with the adopted solution!

      Just wonder if one of the eight admin color schemes could be called High Contrast and use a yellow on black color set. I have been battling the gray on white and gray on black fight with multiple theme developers in multiple CMSs for several years. It would be curious to know how many users ever take time to change from the Default admin color scheme.

      • esmi 7:12 pm on June 20, 2014 Permalink | Log in to Reply

        Helen and I have talked briefly about this before. The idea was that, as the admin skinning system matured, there would be more opportunities to provide low and high contrast admin skins via plugins, if necessary. It’s certainly something I’ve been wanting to do for years.

    • esmi 7:08 pm on June 20, 2014 Permalink | Log in to Reply

      I’m a big fan of reversing background and foreground colors, so in the example screenshot you posted above, I’d want to see something like a blue background with black/dark grey text.. It’s got to really “pop” for sighted keyboard navigators. triangle indicators are very nice as added features for onhover but I’d argue that they’re too subtle for focus highlighting. Ditto for underlines. General rule of thumb: if you have to visually hunt for the currently focused element, then you need something else.

      • Joseph Karr O'Connor 9:35 pm on June 20, 2014 Permalink | Log in to Reply

        So you and @jebswebs support a high and a low contrast admin color scheme which is a different path from devising a solution just for the left navigation that persists through all color schemes? I’m very interested in this idea, wonder if enough people will discover the feature. I think we still need robust focus indicators throughout admin, but support additional accessibility color schemes.

    • David A. Kennedy 2:35 pm on June 25, 2014 Permalink | Log in to Reply

      As I’ve said in our previous team meetings, I’m in favor of a suitable baseline for all color schemes. Although, I love the idea of specialized high contrast themes in addition to that.

    WordCamp SF 2014 

    Howdy, accessibility team! We’re getting ready to publish details about the plans for WordCamp San Francisco this October (which includes the opportunity for a mini team meetup), so if you’re thinking of attending, please read the post at http://make.wordpress.org/updates/2014/06/12/wordcamp-san-francisco-travel-contributor-days/ and take the short survey linked at the end of it so I’ll know how many team members to plan for. Don’t worry, this isn’t a commitment or anything, I just need to get some rough numbers for budgeting purposes (we’re doing a travel assistance program this year, if that makes a difference). Thanks!

    Theme Review Accessibility Guidelines Update 

    In anticipation of WordPress 4.0, I’ve been working on revising the Theme Review accessibility guidelines. With the release of WordPress 4.0, the theme review accessibility guidelines will no longer be considered “draft” guidelines.

    My goal is two fold: first, to make them easier to understand by adding examples, and second, to reorganize them so that the most commonly encountered issues in themes are listed first.

    Additionally, I’m adding a section for “recommended” guidelines.

    Please review the draft of the updates and make comments on this post. Thanks!

     
    • bobeaston 11:34 am on June 13, 2014 Permalink | Log in to Reply

      This guide just keeps getting better and better. It hits the big issues, yet stays concise enough to be approachable. In a previous life, I watched a guide like this grow from a few pages that were useful to one with nearly a thousand pages that no one wanted to open. You’re on exactly the right path for keeping it useful.

      I imagine you might have plans for the following, but if not, I suggest:
      Add a very liberal sprinkling of reference links throughout the guide. People who work with accessibility issues day in and day out know where to quickly find many of the things mentioned in the guide, but your target audience may not. Help them find the quickest route to things like ” the W3C alt text decision tree,” ARIA techniques, etc.

    • Joe Dolson 2:55 pm on June 13, 2014 Permalink | Log in to Reply

      There should be a link for the alt text decision tree; I failed to copy that over from the current version. Whoops! I’ll get that fixed.

      Liberally sprinkling links is definitely an aim; I’ve started on that, but specific suggestions of resources are always welcome. I don’t want to overwhelm with links, either, of course.

      Thanks for your comments! Keeping it short and understandable has been one of the major goals from the beginning.

    Accessibility Team Update: June 11, 2014 

    New Accessible Theme

    Joe Dolson is working on a new accessible theme for the Cities series using an innovative modular approach for accessibility by gathering up accessibility concepts into separate files.

    Joe says:

    “I’m explicitly placing all the accessibility-specific code into a11y.php and a11y.js, to make them easy to find. This is intended to be a useful resource for theme developers, so I want everything to be easy to find.”

    Also of note is skiplinks.js which fixes a bug in WebKit. Simply using an anchor link for the skiplink isn’t enough for WebKit, because keyboard focus will not follow visual focus without Javascript. Joe will be presenting this new theme in a session at WordCamp Chicago this weekend.

    Accessibility Theme Check Process Enhanced

    We are aware that a few themes that are not accessible have arrived in the theme directory with the #accessibility-ready tag. Perhaps the theme creators misunderstood the tag or copied it from another theme without thinking. We got a message from someone who knows accessibility that he bought a theme based on the fact that the free version has the #accessibility-ready tag. Expecting it to be accessible, he was disappointed. Contacting the theme creator he found out that they will be uploading a new free version without the tag.

    Joe Dolson on the process:

    “We’re still struggling with themes getting through the process without getting audited, but we have a recourse for this now. The official policy is to give the author notification that their theme needs to go through the accessibility-ready review to keep the tag, and that they have 72 hours to begin rectification – either by uploading a new version without the tag or by uploading a new version that will begin the process of meeting the accessibility-ready requirements. After 72 hours without a response, the theme will be suspended from the theme repository.”

    Unification of Visual Focus Indication

    It is essential to provide a visual cue to sighted keyboard-only users letting them know where they are on the page. There is no standard look for visual focus indicators. The issue is made more complex because user agents approach this in different ways. @helen talked with us last week and this week again about the fact that the visual look of focus indicators is not unified, and in some instances is not perceivable. For example, on the Media Library screen this is a screenshot showing “apply” button with dotted line focus indicator active and it is not perceivable. One tab press to the right of the “apply” button is the “All dates” select menu selected with a screenshot showing “All dates” select menu with blue glow and dotted line.

    The base look might be the approach taken by WebKit, a blue glow. A base look with more than one element is what we seek. Even if the color blue cannot be perceived there is still the glow. This week we have a goal of organizing the approach to the UI in such a way that the visual focus indicators are unified and perceivable.

     
    • _Redd 8:37 pm on June 18, 2014 Permalink | Log in to Reply

      Hi, everyone, regarding the Unification of Visual Focus Indication, and the meeting today (June 18), I found an example of what I was talking about with using icons to demonstrate a change of focus in the left-hand nav menu.

      http://tympanus.net/Development/IconHoverEffects/#set-1

      Here, the icons “reverse” dark and light areas, and also have additional visual indicators that show the item has received focus. A picture is worth a thousand words, and this example says it far better than I could.

    • _Redd 8:53 pm on June 18, 2014 Permalink | Log in to Reply

      Whoops! Follow Up!

      These icons undergo changes when hovered over, not when receiving focus. The idea of course is that we could develop css to perform similarly when the item receives focus.

    Accessibility Team Update: May 7, 2014 

    Global Accessibility Awareness Day

    I will be talking about WordPress accessibility here in Santa Monica at Yahoo! to celebrate Global Accessibility Awareness Day (GAAD) on May 15. There are many events happening all over the world, perhaps there’s one close to you. If you want to celebrate GAAD but don’t have an event nearby, then here’s a suggestion from Deborah Edwards-Onoro, a front-end WordPress web developer and user experience pro: use only your keyboard for navigation for one hour.

    Automated Accessibility Testing

    It is necessary for me to point out that the very best enterprise-strength automated accessibility checking environments can only accurately report out about thirty percent of the errors. Nonetheless, automated testing, especially command-line testing, will be a valuable addition to the test environment, and we need to explore this. The Netherlands has a commitment to making sure that government sites are accessible, so they are supporting the development of Quail an open-source, MIT-licensed suite of tests that assess web page structure and content. The library is currently developed against WCAG and Section 508 accessibility standards. Accessibility team member David A. Kennedy wrote a great post, “WordPress needs automated accessibility testing” in which he mentions Quail and another tool, pa11y, and I recommend reading what he has to say on the topic.Thanks to David for creating a discussion on this vital topic. David was interviewed by WP Tavern this week and we look forward to seeing that posted soon.

    Tenon

    Karl Groves, another accessibility team member, is working on tenon.io, which is in beta now and promises to be a very powerful accessibility checking tool. While Tenon will be proprietary, Karl tells me that: “We are going to have a Free for Open Source program. As long as the project using Tenon is open source, the account is free.”

    Collaboration

    While there is no doubt that the accessibility team can and must improve collaboration with other WordPress teams, we are also interested in creating ways to expand our reach through innovation and also by collaboration with people doing similar work outside of WordPress. Automated testing is one way to innovate. We saw that the Quail project has created an accessibility module to work within Drupal so we invited Mike Gifford, a Drupal 8 Core Accessibility Maintainer, to our meeting this week to learn about the Drupal accessibility operation. According to Mike “Just to be clear about the automated (accessibility) testing & Drupal. It will be a great addition in the future, it’s found some interesting bugs when we have applied it, but it really has only been marginally useful thus far.” Mike agreed to share info and join forces with us where our interests are similar and we look forward to collaborating with his team and with accessibility teams for other projects.

    WordPress needs automated accessibility testing 

    The Make WordPress Accessibility Team needs help wrapping its arms around WordPress Core as new features get created while helping refine the existing codebase to make it more accessible to people with disabilities. Our small team can’t be everywhere and test everything, but we’re working to gather an accurate picture of what needs our help the most.

    Once we have a better idea of what needs our attention the most, how do we maintain a good grasp of it? Automated accessibility testing can help in a big way here, and I’d like to start working to incorporate it into Core. I brought this up in our last Accessibility Team chat.

    What’s automated accessibility testing? Similar to unit testing, this would allow developers to run a set of tests during their local development workflow of patches for WordPress via a command line tool. These tests would output results that would alert developers to potential errors and help them fix things like missing alt attributes or unassociated form fields and labels. Automated accessibility testing isn’t perfect and it won’t help us overcome all of our challenges, but it can help us find simple, easy-to-fix errors, alert us to large trouble spots within the codebase that need more manual testing and allow us cover a bit more ground. It’s a nice compliment to the manual testing and education we’ve done so far.

    What do we need to consider when selecting a tool?

    WordPress Accessibility Team member Karl Groves has a nice blog post about this. He says you should consider three things:

    1. Flexibility and Freedom. These tools exist for one reason only: to work for you. Every single second you spend learning the UI, figuring out how to use it, or sifting through results is a second of development time that could go into actually improving the system. The tool must be flexible enough to offer the freedom to use it in any environment by any team of any size in any location.
    2. Accurate. Developers of accessibility tools want to find every single issue they possibly can. This unfortunately often includes things that are, in context, irrelevant or of low impact. They also may require an additional amount of human effort to verify. This is a disservice. Tool vendors need to understand that their clients may not have the time, budget, or knowledge to sift through false positives. The user should be able to immediately eliminate or ignore anything that isn’t an undeniable issue.
    3. Understandable The user of the tool needs to know exactly what the problem is, how much impact the problem has, where it is, and how to fix it. Overly general, overly concise, or esoteric result descriptions are unhelpful. If a tool can find a problem, then it can make intelligently informed suggestions for remediation

    I think these are good goals to try to hit. Ideally, we want something that will have little to no impact on a developer’s workflow, allow us to select different test criteria and deliver accurate results we can act on.

    As research, I’ve spoken to Jesse Beach. She’s a Senior Front End Engineer at Acquia Inc., a Drupal contributor, a contributor to QuailJS (a tool Drupal uses for automated accessibility testing) and a member of the Drupal Accessibility group. She’ll help us look at QuailJS as a possible automated accessibility testing approach. And hopefully, we can share accessibility knowledge between these two awesome open source projects! We talked about what we (WordPress Accessibility Team) want to accomplish with automated testing, how a tool might fit into a WordPress developer’s workflow, the future of QuailJS and a bit about accessibility in our different open source projects.

    One other possibility on the short list of tools besides QuailJS includes Pa11y. We will likely look at others as well.

    Next steps

    • Firm up a list of requirements for a tool
    • Experiment with some tools
    • Meet with Core team members to discuss
    • Develop test criteria

    Your ideas and feedback are welcome!

     
    • Aaron Jorbin 5:55 pm on May 5, 2014 Permalink | Log in to Reply

      I like the idea of expanding our automated tests. For each of the possibilities (QuailJS, Pa11y possibly others), I think it would be good to lay out the requirements, benifits and costs.

      Personally, I would like to see whatever tool we use fit into our existing testing flow. This means that it could be run from the command line so that we can run the tests on travisCI and as a part of the grunt precommit command.

      • David A. Kennedy 3:24 pm on May 7, 2014 Permalink | Log in to Reply

        Integrating into the existing testing flow is a high priority, probably only below selecting a tool that has accurate, configurable tests.

        Do we have guidance on selecting or integrating with tools that may not be fully open source. For instance, maybe the tests we write/modify are all open source, but we hit a third-party api to actually get results that isn’t open source.

        Selecting something that’s fully open source/GPLV2 compatible has preference of course, but I thought the question is worth asking.

      Hi David,

      I’m interested in accessibility, WordPress and testing. I’m a follower of @WPaccessibility and I’ve read the last “Accessibility Team Updates” on the blog. Here are a few information you might find helpful for the topic.

      You could find some help with Tanaguru, an opensource accessibility checker (disclaimer: I’m its creator). Tanaguru offers different kinds of audit like page and site-wide audit, but for the expressed need to test the backoffice of WordPress with ATAG, you could use the “scenario audit”. For short, you record a scenario a user could follow (e.g. creating a post, adding an image, modifying the alt, publishing), and send it to Tanaguru, that in turn replays it. Scenario can be replayed when you want. (Technically speaking, it is based on bricks of Selenium.)

      For the needs of automation, you can also plug it with continuous integration tools. We are actually playing with our own Jenkins (that we use for building Tanaguru).

      Here are a few links (hope they’re ok for comments):

      We know a bit WordPress as it runs our corporate site and our blog. I’d be really happy to contribute to “Make WP Accessible”.

      Hope to exchange with you soon on the subject

      Matthieu

        Hi Matthieu,

        Thanks for your comment and for filling us in about Tanaguru. It definitely sounds like it should be on the list. I’ll add it and we’ll take a closer look once we get to that point.

        My contact info is on my site. Feel free to reach out.

    Update on WordCamp accessibility planning 

    I had a great conversation with Andrea Middleton at WordCamp Minneapolis this weekend, and we’re making some plans to work on the core accessibility features that WordCamp organizers will need to pay attention to in building their sites.

    Some of the key tasks will include working through the accessibility issues in the base themes available for WordCamp organizers to build from, providing some documentation to help organizers know what design standards they need to meet, and doing some basic training on checking their work.

    Accessibility Team Update: April 23, 2014 

    Authoring Tool Accessibility Guidelines Testing

    Jeanne Spellman (http://www.w3.org/People/jeanne/), W3C, joined us for the meeting to discuss the Authoring Tool Accessibility Guidelines (ATAG) testing we will be doing on trunk starting May 12. ATAG testing is, in part, useful for guiding development of accessible “software for generating websites, for example, content management systems (CMS).”

    ATAG Overview

    The Authoring Tool Accessibility Guidelines (ATAG) Overview explains how ATAG testing will:

    • help make authoring tools themselves accessible, so that people with disabilities can create web content, and
    • help authors create more accessible web content — specifically: enable, support, and promote the production of content that conforms to Web Content Accessibility Guidelines (WCAG).

    ATAG Testing Harness

    The W3C is developing an automated way to deliver ATAG test instructions and test result tracking and reports. It will also display WCAG test instructions and techniques, where applicable. In the the overall test instructions doc that was used when developing the tests there are general instructions at the top, followed by a table with the ATAG success criteria, and the test(s) for each one. As we are testing to WCAG level AA so will we be testing to ATAG level AA.

    Process

    Jeanne has about 15 volunteer testers. Thank you Jeanne! She explained the process: “We set up a page of accessible content, and a page of inaccessible content. Then we have a page of different types of content – video, audio, tables. Some of the ATAG tests check to see if WordPress breaks accessible content, while others see if WordPress fixes inaccessible content.” We discussed access to a test instance of WordPress trunk which is ready to go thanks to Rian Rietveld. There is no estimate as to how long the testing will take since it is a new process.

    Helping WordPress and the W3C

    This process will help improve WordPress and it will also help make ATAG 2.0 a finalized W3C standard. We are testing to WCAG level AA so we will be testing to ATAG level AA which will help the W3C process. Jeanne explained: “The writing is all done, and now we just need to prove to W3C management that there are 2 real world examples of every success criteria and 5 authoring tools have implemented ATAG level A.  AA is a huge bonus.”

    Accounts and Trac

    We noted that the volunteer testers will all need WordPress accounts. Aaron Jorbin very thoughtfully posted the core handbook link to working with trac and opening a ticket. Joe Dolson noted that: “It (testing) doesn’t have to be finished to be able to create tickets – we should be ticketing every discovery as we move forward.” The W3C team will be able to pull reports of all the errors from the testing harness tool which should facilitate the process.

    Accessibility Team Update: April 16, 2014 

    Team Member Thanks

    Thanks all the other teams who participated in making WordPress 3.9 happen and who reached out to the accessibility team for assistance. Many more people are asking us to check things than ever before. Special thanks to accessibility team members David A. Kennedy, Graham Armfield, and Joe Dolson who are mentioned in the 3.9 credits.

    Weekly Meeting Time

    There’s always confusion when the time changes and I regret that I compounded the confusion by being confused myself. I’m now using StatusClock.app by Pulsely for OS X set to GMT/UTC so I’ll be sure to call the weekly meeting to order at 19:00 UTC.

    Previous Test

    When the accessibility team did the last round of testing it was intended that it be done over a short period of time, but due to various factors it spread out over two months. That was a keyboard-only test because we were certain that, given our resources, we could not finish a full test. It turns out we could not finish even the attenuated test in a reasonable amount of time. This was not the intended outcome but I learned that we need many more testers to perform the testing in an effective manner. This is why I was very glad to make a testing plan with Jeanne Spellman of the W3C when we were at the International Technology and Persons With Disabilities Conference a month ago.

    New Test Round

    Jeanne Spellman of the W3C, the team contact for the User Agent Working Group and the Authoring Tool Accessibility Guidelines Working Group (AUWG), has committed to helping us test WordPress trunk using the Authoring Tool Accessibility Guidelines (ATAG). Jeanne has assembled a good number of volunteers to do the testing and they will file tickets or bump things up to me as soon as they have identified an issue. This time I feel confident that with current team members providing guidance the W3C team will be able to accomplish the task in a short enough period of time to be most effective. Testing is now scheduled to start the week of May 12, 2014.

    ATAG

    For those not familiar with ATAG, it is primarily for developers of authoring tools including software for generating websites such as content management systems. There are two areas of focus: making sure that the authoring tool user interface is accessible, and that the authoring tool supports the production of accessible content. Just as with WCAG 2.0, ATAG has three levels of success criteria in order of increasing compliance: A, AA, and AAA. We are testing to WCAG 2.0 level AA so it follows that the ATAG testing will also be done to level AA. ATAG testing will help us discover the issues we need to address next. ATAG at a Glance provides a short summary of the accessibility principles and guidelines in ATAG 2.0.

    Update on accessibility-ready theme tag 

    We’re gradually working the kinks out of the process. There was an oversight in the automated process that added the accessibility-ready keyword to themes, so that only new themes were automatically getting the keyword, and not updated themes that added it. That’s been fixed, which will improve our ability to note themes that need to go through the review process.

    There’s a lot of support for the process, and the theme review team is invested in making this work, but I could use some backup in actually doing the reviews. Even if you don’t have the accessibility background, let me know if you’re interested: I’m happy to provide training to make sure you’ve got the knowledge it takes to do this review.

     
    • David A. Kennedy 4:00 pm on April 16, 2014 Permalink | Log in to Reply

      @joedolson I can help out with this once I finish up a few other projects. It’s a good place for me to contribute since it’s theme-centric. Feel free to reach out to me with details on how to get started.
