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”.
End tag “div” seen, but there were open elements.
Unclosed element “span”.
Attribute “value” not allowed on element “input” at this point.
Element “input” is missing required attribute “alt”.
Bad value “javascript://” for attribute “href” on element “a”: missing } after function body
Attribute “href” not allowed on element “span” at this point.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Malformed byte sequence: “e7”.
Malformed byte sequence: “ae”.
Element “option” without attribute “label” must not be empty.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
