Compliance status

This website is partially compliant with the Web Content Accessibility Guidelines version 2.1 AA standard, due to the non-compliances listed below.

Non-accessible content

The content listed below is non-accessible for the following reasons.

Non-compliance with the accessibility regulations

Some links do not clearly explain where they lead, or that they lead to external sites. This fails WCAG 2.1 success criteria 2.4.4 Link Purpose (In Context).

Some pages have redundant links. This is not a fail, but should be looked at under WCAG 2.1 success criterion 2.4.4 Link Purpose (In Context).

There are some images which contain text, and a text-only alternative is not available. This fails WCAG 2.1 success criterion 1.4.5 (Images of Text).

There are parts of this documentation that are not accessible because of issues caused by our Technical Documentation Template.

For example, some code examples use a colour that has very low contrast with the background colour, so the code may be difficult to see. This fails WCAG 2.1 success criterion 1.4.3 - Contrast (Minimum).
