Errors:
No “li” element in scope but a “li” end tag seen.
Bad value “150px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
Start tag “a” seen but an element of the same type was already open.
Stray end tag “div”.
Attribute “border” not allowed on element “div” at this point.
Bad value “noopener no” for attribute “rel” on element “a”: The string “no” is not a registered keyword.
