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Using the “meta” element to specify the document-wide default language is obsolete.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.
Start tag “head” seen but an element of the same type was already open.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
The “cellpadding” attribute on the “table” element is obsolete. Use CSS instead.
The “align” attribute on the “table” element is obsolete. Use CSS instead.
The “valign” attribute on the “td” element is obsolete. Use CSS instead.
The “font” element is obsolete. Use CSS instead.
Attribute “target” not allowed on element “img” at this point.
