Element “meta” is missing one or more of the following attributes: “content”, “property”.
Bad value “https://fonts.googleapis.com/css?family=Merriweather:700italic|Oswald|Istok+Web:400,700” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Bad value “” for attribute “id” on element “body”: An ID must not be the empty string.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “src” not allowed on element “header” at this point.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Warnings:
Attribute “)"” is not serializable as XML 1.0.
