HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:fb” not allowed here.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “span”.
Duplicate ID “widget-ShareThis_ShareThis”.
Attribute “allow” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “summary” attribute on the “table” element is obsolete. Consider describing the structure of the “table” in a “caption” element or in a “figure” element containing the “table”; or, simplify the structure of the “table” so that no description is needed.
Warnings:
Attribute with the local name “xmlns:fb” is not serializable as XML 1.0.
The first occurrence of ID “widget-ShareThis_ShareThis” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
