Errors:

Bad value “https://fonts.googleapis.com/css?family=Oswald&text=0123456789./\%” for attribute “href” on element “link”: Illegal character in query: “\” is not allowed.
Element “spn” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Attribute “duration” not allowed on element “div” at this point.
Attribute “bid” not allowed on element “div” at this point.
Attribute “aid” not allowed on element “div” at this point.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No “p” element in scope but a “p” end tag seen.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “complementary” role is unnecessary for element “aside”.
Empty heading.
