Day 3: WCAG Perceivable, Part 2
Time spent studying today: 1 hour. Again, another weekend day that I successfully allotted time for study. I've been through three rounds of 100 Days of Code, a 9-month course on Udacity, and one round of 100 Days of A11y. I'm no stranger to dedicating time, figuring out a process, and sacrificing blocks of time I could've spent with family. However, I've seen what I can accomplish and how I can progress, so that gives me some confidence in continuing to put time aside to prepare in-depth for this challenging exam.
Things I accomplishedPermalink for "Things I accomplished"
- Closely read through all of the perceivable principle's success criteria
- Memorized the 4 guidelines under the perceivable principle:
- Text alternatives
- Time-based media (audio, video)
- Added to my POUR spreadsheet to include more techniques

9 out of the 29 success criteria in the first WCAG principle are Level A. It's like reading, "these are just the basics, folks, which gets you almost a third of the way there". Yet if they're so basic, why aren't all web designers and developers trained to meet the bare minimum to create websites that are better for everyone? Is it really so much to ask for alternative text for images, captions for video, or volume controls for audio?
Other new-to-me tidbits:
- Logos and brand names are exempt from Contrast criterion (SC 1.4.3) and Images of text (SC 1.4.5).
- Captions and images of text are exempt from the new Resize Text criterion (SC 1.4.4).
- There's a suggestion for appropriate audio contrast when it comes to foreground and background noise (see SC 1.4.7)
