Number of error type: 7 3.60
Number of errors: 21 2.90

Problems:

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 2.19:1. Recommendation: change text colour to #767676.
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 4.2:1. Recommendation: change text colour to #73777d.

Heading tag found with no content. Text that is not intended as a heading should not be marked up with heading tags.
A fieldset element does not have a name available to an accessibility API. Valid names are: legend element, aria-label undefined, aria-labelledby undefined.
