Almost standards mode 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”.

Using the “meta” element to specify the document-wide default language is obsolete.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

The “width” attribute on the “td” element is obsolete.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

The “align” attribute on the “table” element is obsolete.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

The “border” attribute on the “table” element is obsolete.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

The “hspace” attribute on the “img” element is obsolete.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

The “cellpadding” attribute on the “table” element is obsolete.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

The “bgcolor” attribute on the “table” element is obsolete.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

The “align” attribute on the “tr” element is obsolete.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

The “font” element is obsolete.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

Table column 2 established by element “td” has no cells beginning in it.

Warnings

The “border” attribute is obsolete.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

The “name” attribute is obsolete.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

A table row was 3 columns wide, which is less than the column count established by the first row (4).
