HTML markup errors and warnings
(Rescan now...)
Errors:
Internal encoding declaration “us-ascii” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=US-ASCII” for attribute “content” on element “meta”: “us-ascii” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
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.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “style” not allowed as child of element “header” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
No “p” element in scope but a “p” end tag seen.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The “navigation” role is unnecessary for element “nav”.
Empty heading.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
