Errors:
Malformed byte sequence: “d6”.
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”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Malformed byte sequence: “f6”.
Malformed byte sequence: “e4”.
Malformed byte sequence: “fc”.
The “hspace” attribute on the “img” element is obsolete. Use CSS instead.
The “vspace” attribute on the “img” element is obsolete. Use CSS instead.

End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
The “language” attribute on the “script” element is obsolete. You can safely omit it.
