Add tags for WCAG 2.1 SCs

[yatil]

Task description:

The objective is to add tags to the new WCAG 2.1 Success Criteria as listed here. We have tags for four different roles:

• Developing (dev)
• Interaction Design (int)
• Visual Design (vis)
• Content Creation (con)

Looking at the current 1.1.1 Non-text content success criterion, it has the following tags attached:

non-text-content:
  dev: captcha images text-alternatives video
  int: audio video buttons carousels captcha
  vis: images images-of-text animation progress-steps text-alternatives video
  con: audio captions content images live-stream moving-content text-alternatives video visual-cues buttons

For 1.3.4 Orientation, it might be only applicable to developers and visual designers, the former need to think about it when programming the site the latter must design for different orientation. It also mostly applies to mobile and rotation. They can be addressed with responsive design. A tag set for Orientation might look like this:

non-text-content:
  dev: mobile rotation responsive
  int: 
  vis: mobile rotation responsive
  con: 

How to edit tasks:

1. Edit tags in this file and replace the following placeholder tags for the respective success criterion:

   dev: 1-needs-dev-tags
   int: 1-needs-int-tags
   vis: 1-needs-vis-tags
   con: 1-needs-con-tags

2. The Quickref will then be regenerated and you can preview it. (Wait until it says “All checks have passed” and “deploy preview ready” in the box below.)
