HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
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 “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Bad value “ubermenu-main-Academic menu” for attribute “id” on element “nav”: An ID must not contain whitespace.
Bad value “ubermenu-nav-main-Academic menu” for attribute “id” on element “ul”: An ID must not contain whitespace.
Element “p” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
End tag “p” implied, but there were open elements.
Unclosed element “span”.
Stray end tag “span”.
No “p” element in scope but a “p” end tag seen.
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
