Drafts

Current

updated on 8th December 2021.

We were done with the Phase 1. We copied any existing W3C's materials and paste them to the following Method documents. The W3C materials we reviewed include:

• WCAG 2.1 - SC 1.1.1
• Sufficient Techniques in Understanding WCAG 2.1 - SC 1.1.1
• Web Accessibility Tutorials - Images
• Easy Checks - Image text alternatives ("alt text")
• HTML specification - 4.8.4.4 Requirements for providing text to act as an alternative for images

Note that we haven't edited/modified/added/removed anything at all. We just copied and pasted them to show how SC in WCAG 2.x will be migrated to WCAG 3.
