Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-15” disagrees with the actual encoding of the document (“utf-8”).
Malformed byte sequence: “e8”.
Bad value “none” for attribute “role” on element “li”.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
Malformed byte sequence: “ea”.
The “align” attribute on the “img” element is obsolete. Use CSS instead.

Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “navigation” role is unnecessary for element “nav”.
“role="none"” is not yet supported in all browsers. Consider instead either using “role="presentation"” or “role="none presentation"”.
