HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Stray end tag “ul”.
The element “h1” must not appear as a descendant of the “address” element.
The element “h2” must not appear as a descendant of the “address” element.
Duplicate ID “searchform”.
Warnings:
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).
The first occurrence of ID “searchform” was here.
The “type” attribute is unnecessary for JavaScript resources.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
