Day 2: WCAG Perceivable, Part 1

Day 2… a weekend day, which can make it harder to make time to set aside for studying. I did it, though, spending roughly an hour and a half working through documentation, mulling over only part of the first WCAG principle, and working toward visualizing the different guidelines, success criterion, and techniques. I didn’t get as far as I would’ve liked either, yet this is the deepest work I’ve ever done at combing through the WCAG docs.

Things I accomplished

  • Read through the Perceivable principle in WCAG 2.1 documentation (normative and non-normative).
  • Started a spreadsheet to visualize relationships between principles, guidelines, success criterion, and techniques. Specifically I mapped out the perceivable principle.
  • Discovered techniques that failed to meet criterion within the perceivable principle.
  • Dug into helpful solutions to common situations (satisfactory techniques) via W3C’s “How to Meet WCAG 2.1“. Seriously, this resource is extremely helpful for all those situations I’ve had to figure out how to be more inclusive, and the documentation is there to back up my decision when I have to present it to my team!

What I learned today

In the process of trying to memorize guidelines and success criterion, I reinforced the image of the layers that exist within WCAG:

Additionally, looking closer at each criterion helped me to identify the additions made to WCAG 2.0’s first principle:

  • Orientation
  • Identify input purposes
  • Identify purpose
  • Reflow
  • Non-text contrast
  • Text spacing
  • Content on hover or focus

When reading through the description about text alternatives, I ran across a concept new to me: “simpler language” is considered a text alternative under Guideline 1.1. Also, there are some identified exceptions to the text alternative guideline. Those exceptions apply to:

  • controls or input fields
  • time-based media
  • tests/exams
  • specific sensory experiences
  • CAPTCHA
  • decorative images or typography

Day 1: Initialization and WCAG Introduction

And here I go! To start off my journey to earn my Web Accessibility Specialist certification, I had to get myself in gear, get organized, and just start.

Things I accomplished

  • Launched this WordPress blog to make myself accountable to commit daily to web a11y study.
  • Set up a Google Calendar to keep myself on track to complete 80% of study materials by March 10, 2019, and beyond to April 3rd, when my exam happens (see my “How to Succeed” widget.
  • Read through WCAG 2.1 introduction non-normative).

What I learned today

Pyramid with 4 Principles as the foundation, 13 Guidelines, Success Criteria, and, lastly, Techniques.

  • WCAG layers of guidance include:
  • WCAG 2.1 updated 2.0 to be more inclusive of:
    • users with cognitive or learning disabilities,
    • users with low vision, and
    • users with disabilities on mobile devices
  • 17 new success criteria were appended to WCAG 2.0:
    • 1.3.4 Orientation (AA)
    • 1.3.5 Identify Input Purpose (AA)
    • 1.3.6 Identify Purpose (AAA)
    • 1.4.10 Reflow (AA)
    • 1.4.11 Non-Text Contrast (AA)
    • 1.4.12 Text Spacing (AA)
    • 1.4.13 Content on Hover or Focus (AA)
    • 2.1.4 Character Key Shortcuts (A)
    • 2.2.6 Timeouts (AAA)
    • 2.3.3 Animation from Interactions (AAA)
    • 2.5.1 Pointer Gestures (A)
    • 2.5.2 Pointer Cancellation (A)
    • 2.5.3 Label in Name (A)
    • 2.5.4 Motion Actuation (A)
    • 2.5.5 Target Size (AAA)
    • 2.5.6 Concurrent Input Mechanisms (AAA)
    • 4.1.3 Status Messages (AA)
  • An overhaul of WCAG is coming in a few year. In the meantime, 2.1 is the current recommendation, and 2.2 will be recommended shortly after that, before the new changes happens.

Journey to Learn All Things Web Accessibility Begins

“The more that you read, the more things you will know. The more that you learn, the more places you’ll go.”
Dr. Seuss, I Can Read With My Eyes Shut!

Thanks for coming! I’m here to learn web accessibility at a greater depth, so that I can become a Web Accessibility Specialist. In 100 days I plan to be (mostly) prepared for IAAP’s Web Accessibility Specialist certification exam. Along the way, I’d like to share with you what I learn each day.

Join me on my journey to learn about all things web accessibility from W3C documentation to user stories.
