Errors:
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.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “language” for attribute “http-equiv” on element “meta”.
Attribute “value” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “content”, “property”.
Bad value “//fonts.googleapis.com/css?family=Roboto:400,400i,500,700|Roboto+Condensed:700|Material+Icons” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Attribute “alt” not allowed on element “a” at this point.
“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.

Warnings:

The “contentinfo” role is unnecessary for element “footer”.
