HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “true” for attribute “selected” on element “option”.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “true"” for attribute “selected” on element “option”.
The “select” element cannot have more than one selected “option” descendant unless the “multiple” attribute is specified.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “width” not allowed on element “input” at this point.
Element “input” is missing required attribute “alt”.
Element “p” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
The “font” element is obsolete. Use CSS instead.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
