HTML markup errors and warnings
(Rescan now...)
Errors:
Duplicate attribute “rel”.
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
Bad value “” for attribute “src” on element “iframe”: Must be non-empty.
The “allowtransparency” attribute on the “iframe” element is obsolete. Use CSS instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
No “li” element in scope but a “li” end tag seen.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “a” violates nesting rules.
No space between attributes.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “_blank"” for attribute “target” on element “a”: Reserved keyword “blank"” used.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “itemprop” attribute was specified, but the element is not a property of any item.
