HTML markup errors and warnings
(Rescan now...)
Errors:
Using the “meta” element to specify the document-wide default language is obsolete.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 “action” on element “form”: Must be non-empty.
Attribute “placeholder” not allowed on element “form” at this point.
Attribute “tab” not allowed on element “span” at this point.
The “font” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Attribute “data” not allowed on element “script” at this point.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
