Errors

Obsolete doctype. Expected “<!DOCTYPE html>”.

The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.

Bad value “short icon” for attribute “rel” on element “link”: The string “short” is not a registered keyword.

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The “alink” attribute on the “body” element is obsolete. Use CSS instead.

The “bgcolor” attribute on the “body” element is obsolete. Use CSS instead.

The “link” attribute on the “body” element is obsolete. Use CSS instead.

The “text” attribute on the “body” element is obsolete. Use CSS instead.

The “vlink” attribute on the “body” element is obsolete. Use CSS instead.

The “center” element is obsolete. Use CSS instead.

The “font” element is obsolete. Use CSS instead.

The “width” attribute on the “hr” element is obsolete. Use CSS instead.

Element “li” not allowed as child of element “blockquote” in this context. (Suppressing further errors from this subtree.)

The “tt” element is obsolete. Use CSS instead.

Warnings

The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
