- The website can be more accessible, but is rather good!

Accessibility section:
- Number of types of issues: 4 4.20

- Heading tag found with no content. Text that is not intended as a heading should not be marked up with heading tags.
- Anchor element found with a valid href attribute, but no link content has been supplied.
- Iframe element requires a non-empty title attribute that identifies the frame.
- A element has insufficient contrast at this conformance level. Expected a contrast ratio of at least 4.5:1, but text in this element has a contrast ratio of 1:1. Recommendation: change text colour to #767676.
