Errors

Bad value “Expires” for attribute “http-equiv” on element “meta”.

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”.

No space between attributes.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

The “align” attribute on the “img” element is obsolete. Use CSS instead.

Bad value “2” for attribute “border” on element “img”: Only “0” is a permitted zero literal.

The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.

Stray end tag “tr”.

Element “script” must not have attribute “charset” unless attribute “src” is also specified.

The “aria-labelledby” attribute must point to an element in the same document.

The hash-name reference in attribute “usemap” referred to “toolmap”, but there is no “map” element with a “name” attribute with that value.

Warnings

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.

This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
