HTML markup errors and warnings
(Rescan now...)
Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “div” seen, but there were open elements.
Unclosed element “ul”.
Element “blink” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Attribute “pubdate” not allowed on element “time” at this point.
Attribute “alt” not allowed on element “input” at this point.
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The “frameborder” attribute on the “iframe” element is obsolete.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.
Duplicate ID “poll_links”.
Warnings:
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The first occurrence of ID “poll_links” was here.
This document appears to be written in Indonesian but the “html” start tag has “lang="en-gb"”. Consider using “lang="id"” (or variant) instead.
