HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “charset” attribute on the “script” element is obsolete.
The value of attribute “alt” on element “img” from namespace “http://www.w3.org/1999/xhtml” is not in Unicode Normalization Form C.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Errors:
The element “h3” must not appear as a descendant of the “dt” element.
Attribute “value” not allowed on element “input” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The only allowed value for the “charset” attribute for the “script” element is “utf-8”. (But the attribute is not needed and should be omitted altogether.)
