Errors

A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.

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

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

Duplicate ID “btnallcourses”.

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

Bad value “” for attribute “action” on element “form”: Must be non-empty.

The element “label” must not appear as a descendant of the “a” element.

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

Duplicate ID “login-fields”.

Bad value “button” for attribute “type” on element “a”: Subtype missing.

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

Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).

Empty heading.

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

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
