The accessibility is apparently really bad! Probably both for disabled people and everyone of us when we need some accessibility!
Number of error type: 8 3.40
Number of errors: 22 2.80

Problems:

A emailinput element does not have a name available to an accessibility API. Valid names are: label element, title undefined, aria-label undefined, aria-labelledby undefined.
Anchor element found with a valid href attribute, but no link content has been supplied.
A textinput element does not have a name available to an accessibility API. Valid names are: label element, title undefined, aria-label undefined, aria-labelledby undefined.
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 3.71:1. Recommendation: change text colour to #006ee4.
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 3.9:1. Recommendation: change text colour to #767676.
A textarea element does not have a name available to an accessibility API. Valid names are: label element, title undefined, aria-label undefined, aria-labelledby undefined.
A form field should be labelled in some way. Use the label element (either with a "for" attribute or wrapped around the form field), or "title", "aria-label" or "aria-labelledby" attributes as appropriate.
