(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:b” not allowed here.
Attribute “xmlns:data” not allowed here.
Attribute “xmlns:expr” not allowed here.
Bad value “service.post” for attribute “rel” on element “link”: The string “service.post” is not a registered keyword.
Bad value “none” for attribute “media” on element “link”: Media query ended prematurely.
The “center” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Attribute “trbidi” not allowed on element “div” at this point.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Warnings:
Attribute with the local name “xmlns:b” is not serializable as XML 1.0.
Attribute with the local name “xmlns:data” is not serializable as XML 1.0.
Attribute with the local name “xmlns:expr” is not serializable as XML 1.0.
The “name” attribute is obsolete.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The “border” attribute is obsolete.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.
This document appears to be written in Arabic. Consider adding “lang="ar"” (or variant) to the “html” start tag.
