- The website can be more accessible, but is rather good!
Accessibility section:
- Number of types of issues: 6 3.80
- Number of issues: 8 4.20
##### Problems:
- Duplicate id attribute value "searchWidgetTrigger" found on the web page.
- A link points to a named anchor "content" within the document, but no anchor exists with that name.
- Iframe element requires a non-empty title attribute that identifies the frame.
- 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.
- 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.
- The html element should have a lang or xml:lang attribute which describes the language of the document.
