HTML markup errors and warnings
(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “20px” for attribute “size” on element “input”: Expected a digit but saw “p” instead.
Duplicate attribute “class”.
Attribute “name” 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.)
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Bad value “257px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Bad value “171px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
Attribute “type” not allowed on element “menu” at this point.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
End tag “div” seen, but there were open elements.
Unclosed element “span”.
Stray start tag “script”.
Warnings:
The “banner” role is unnecessary for element “header”.
Empty heading.
The “contentinfo” role is unnecessary for element “footer”.
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).
