HTML markup errors and warnings
(Rescan now...)
Errors:
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”.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Element “div” not allowed as child of element “label” in this context. (Suppressing further errors from this subtree.)
Stray end tag “label”.
The “label” element may contain at most one “button”, “input”, “meter”, “output”, “progress”, “select”, or “textarea” descendant.
End tag “form” seen, but there were open elements.
Unclosed element “label”.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
“label” element with multiple labelable descendants.
