HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Obsolete doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “content-style-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Using the “meta” element to specify the document-wide default language is obsolete.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.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
Table column 2 established by element “td” has no cells beginning in it.
Attribute “value” not allowed on element “input” at this point.
Element “input” is missing required attribute “alt”.
The “cellpadding” attribute on the “table” element is obsolete. Use CSS instead.
Warnings:
A table row was 2 columns wide, which is less than the column count established by the first row (3).
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
