HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
No “p” element in scope but a “p” end tag seen.
Attribute “rel” not allowed on element “span” at this point.
Attribute “autocapitalize” not allowed on element “input” at this point.
Attribute “autocorrect” not allowed on element “input” at this point.
Bad value “” for attribute “for” on element “label”: An ID must not be the empty string.
Element “option” without attribute “label” must not be empty.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “generator” for attribute “rel” on element “a”: The string “generator” is not a registered keyword.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
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).
