HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “” for attribute “method” on element “form”.
A slash was not immediately followed by “>”.
End tag had attributes.
Stray end tag “span<”.
End tag “div” seen, but there were open elements.
Unclosed element “span”.
Bad value “” for attribute “id” on element “a”: An ID must not be the empty string.
Duplicate ID “”.
Bad value “true” for attribute “checked” on element “input”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “” 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.
