Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Element “meta” is missing one or more of the following attributes: “content”, “itemprop”, “name”.
Bad value “//fonts.googleapis.com/css?family=Source+Sans+Pro:200,300,400,600,700|Source+Code+Pro:300,400,500,600,700” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
The “target” attribute on the “link” element is obsolete. You can safely omit it.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Attribute “autocorrect” not allowed on element “input” at this point.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “navigation” role is unnecessary for element “nav”.
