No space between attributes.
Duplicate ID “site-container”.
End tag “div” seen, but there were open elements.
Unclosed element “span”.
Element “meta” is missing required attribute “content”.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “fb-root”.

Warnings:
Empty heading.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “site-container” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The first occurrence of ID “fb-root” was here.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
