HTML markup errors and warnings
(Rescan now...)
Errors:
The “charset” attribute on the “link” element is obsolete. Use an HTTP Content-Type header on the linked resource instead.
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 instance of child element “dd”.
Duplicate ID “openId”.
Element “style” not allowed as child of element “main” in this context. (Suppressing further errors from this subtree.)
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
“"” 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.
No space between attributes.
Warnings:
The first occurrence of ID “openId” was here.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
