(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
No space between attributes.
Attribute “ content” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “content”, “property”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “height” not allowed on element “a” at this point.
Duplicate ID “SideNavi”.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Stray end tag “noscript”.
Warnings:
Attribute “ content” is not serializable as XML 1.0.
The “type” attribute is unnecessary for JavaScript resources.
Empty heading.
The first occurrence of ID “SideNavi” was here.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
