HTML markup errors and warnings
(Rescan now...)
Errors:
Stray start tag “html”.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Bad value “_target” for attribute “target” on element “a”: Reserved keyword “target” used.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “” for attribute “id” on element “img”: An ID must not be the empty string.
Duplicate ID “”.
“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The first occurrence of ID “” was here.
