Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

Attribute “http-equiv” not allowed on element “meta” at this point.

Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.

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”.

Element “div” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)

Element “ul” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)

Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)

Bad value “_target” for attribute “target” on element “a”: Reserved keyword “target” used.

The “font” element is obsolete. Use CSS instead.

Warnings

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
