Issues

Strikethrough issues won't be done here (a comment has been added into the description to clarify how they will be processed).

A

1. No label. See:
   • Fig. 5.01.png. This is a false positive. WAVE complains about missing label for a select element that is hidden. not only by visibility: hidden; display: none; style, but also by aria-hidden="true", so nothing will be done here.
   • Fig. 5.02.png
   • Fig. 5.03.png
2. Errors were found using W3C Nu Validation Service and filtered to indicate WCAG errors only. Nothing to do here because these errors will be done in:
   • Duplicate ID for site blocks. Fixed as part of MDL-67969
   • Invalid 'for' attribute for the course selector on the view calendar page. Fixed as part of MDL-67902

AA

1. Colour contrast #3, #4. Will be addressed on MDL-64494

AAA

1. There is a loss of data after a re-authentication. This has been left out as it was AAA and as it required a massive amount of work and a lot of code refactoring
2. Abbreviations such as "Sun", "Mon" etc. are not fully explained. Even well known abbreviations need to either be expanded on the first use on a page or that a link to a glossary or list of terms be provided
