HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “font” element is obsolete. Use CSS instead.
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.)
Bad value “” for attribute “src” on element “img”: Must be non-empty.
Warnings:
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “type” attribute is unnecessary for JavaScript resources.
The “charset” attribute on the “script” element is obsolete.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
