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”.
Bad value “header” for attribute “role” on element “header”.
Element “flow:fileref” not allowed as child of element “li” in this context. (Suppressing further errors from this subtree.)
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “li” seen, but there were open elements.
Unclosed element “flow:fileref”.
Element “wcf:url” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
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:
The “navigation” role is unnecessary for element “nav”.
Element name “flow:fileref” cannot be represented as XML 1.0.
Element name “wcf:url” cannot be represented as XML 1.0.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
