HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “content-script-type” for attribute “http-equiv” on element “meta”.
Bad value “content-style-type” for attribute “http-equiv” on element “meta”.
Start tag “body” seen but an element of the same type was already open.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “style” not allowed as child of element “section” in this context. (Suppressing further errors from this subtree.)
End tag “div” seen, but there were open elements.
Unclosed element “ul”.
Stray end tag “ul”.
No space between attributes.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “allowtransparency” attribute on the “iframe” element is obsolete. Use CSS instead.
Saw “</>”. Probable causes: Unescaped “<” (escape as “<”) or mistyped end tag.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
