HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “Cache-Control” 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Using the “meta” element to specify the document-wide default language is obsolete.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.
A document must not include more than one “meta” element with a “charset” attribute.
CSS: “size”: Property “size” doesn't exist.
The “center” element is obsolete. Use CSS instead.
The “bgcolor” attribute on the “tr” element is obsolete. Use CSS instead.
The element “a” must not appear as a descendant of the “button” element.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
