HTML markup errors and warnings
(Rescan now...)
Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Attribute “autocapitalize” not allowed on element “input” at this point.
Attribute “autocorrect” not allowed on element “input” at this point.
Element “spam” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)
Start tag “a” seen but an element of the same type was already open.
Stray end tag “a”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate attribute “class”.
Attribute “checked” not allowed on element “input” at this point.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
