HTML markup errors and warnings
(Rescan now...)
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>”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “content-style-type” for attribute “http-equiv” on element “meta”.
Bad value “content-script-type” for attribute “http-equiv” on element “meta”.
Duplicate ID “gnav_search”.
Element “a” not allowed as child of element “dl” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Stray end tag “a”.
Bad value “” for attribute “border” on element “img”: Only “0” is a permitted zero literal.
Stray end tag “div”.
Warnings:
The first occurrence of ID “gnav_search” was here.
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The “border” attribute is obsolete.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.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
