HTML markup errors and warnings
(Rescan now...)
Errors:
Quirky doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
The “align” attribute on the “table” element is obsolete. Use CSS instead.
The “font” element is obsolete. Use CSS instead.
The “align” attribute on the “p” element is obsolete. Use CSS instead.
The “tt” element is obsolete. Use CSS instead.
The “align” attribute on the “h2” element is obsolete. Use CSS instead.
The “border” attribute on the “table” element is obsolete. Use CSS instead.
Element “table” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
A table row was 1 columns wide, which is less than the column count established by the first row (2).
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
