Bad value “” for attribute “id” on element “div”: An ID must not be the empty string.
No “p” element in scope but a “p” end tag seen.
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Stray end tag “span”.

Unclosed element “span”.
Duplicate ID “”.
Bad value “” for attribute “width” on element “img”: The empty string is not a valid non-negative integer.

Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “” 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).
