HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
Bad value “cleartype” for attribute “http-equiv” on element “meta”.
Bad value “javascript:void();” for attribute “href” on element “a”: syntax error
Element “form” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Attribute “"style” not allowed on element “div” at this point.
No “p” element in scope but a “p” end tag seen.
The “font” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “ul”.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Attribute “"style” is not serializable as XML 1.0.
Empty heading.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
