A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.

End tag “div” seen, but there were open elements.

Unclosed element “span”.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Element “dl” is missing a required child element.

Attribute “href” not allowed on element “span” at this point.

Element “dl” is missing a required instance of child element “dd”.
