HTML markup errors and warnings
(Rescan now...)
Warnings:
The “form” role is unnecessary for element “form”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
Errors:
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “center” element is obsolete. Use CSS instead.
Bad value “{EDITOR_URL}” for attribute “href” on element “a”: Illegal character in path segment: “{” is not allowed.
Attribute “border” not allowed on element “input” at this point.
Bad character “<” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
