Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.

Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.

Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.

The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.

The “summary” attribute on the “table” element is obsolete. Consider describing the structure of the “table” in a “caption” element or in a “figure” element containing the “table”; or, simplify the structure of the “table” so that no description is needed.

The “valign” attribute on the “tr” element is obsolete. Use CSS instead.
