HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “@"onfocus” not allowed on element “input” at this point.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “header”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “duration” not allowed on element “div” at this point.
No “p” element in scope but a “p” end tag seen.
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
Warnings:
Attribute “@"onfocus” is not serializable as XML 1.0.
The first occurrence of ID “header” was here.
The “border” attribute is obsolete.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The “language” attribute on the “script” element is obsolete.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.
