Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Obsolete doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “content-style-type” for attribute “http-equiv” on element “meta”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Attribute “value” not allowed on element “input” at this point.
Element “input” is missing required attribute “alt”.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
The “border” attribute on the “table” element is obsolete. Use CSS instead.
The “center” element is obsolete. Use CSS instead.
Element “ahref='signup.php'” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Stray end tag “a”.
End tag “div” seen, but there were open elements.
Unclosed element “ahref='signup.php'”.
Warnings:
A table row was 6 columns wide, which is less than the column count established by the first row (7).
Element name “ahref='signup.php'” cannot be represented as XML 1.0.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
