HTML markup errors and warnings
(Rescan now...)
Errors:
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
The element “button” must not appear as a descendant of the “a” element.
Duplicate attribute “class”.
Attribute “rel” not allowed on element “input” at this point.
Element “img” is missing required attribute “src”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Empty heading.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
