Bad value “//fonts.googleapis.com/css?family=Roboto:300,400,600,700|Roboto+Slab:300,700” 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 “rel” not allowed on element “input” at this point.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
