Errors:
Attribute “charset” not allowed on element “meta” at this point.

A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
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 document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Attribute “active” not allowed on element “li” at this point.
The “align” attribute on the “img” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)

Element “ul” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Warnings:
