HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Element “div” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
A slash was not immediately followed by “>”.
End tag had attributes.
Start tag “a” seen but an element of the same type was already open.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “cellpadding” attribute on the “table” element is obsolete. Use CSS instead.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
End tag “td” seen, but there were open elements.
Unclosed element “div”.
Attribute “token” not allowed on element “a” at this point.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
