HTML markup errors and warnings
(Rescan now...)
Errors:
Attribute “charset” not allowed on element “meta” at this point.
Bad value “text/html” for attribute “content” on element “meta”: The legacy encoding declaration did not start with “text/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.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “feed” for attribute “rel” on element “link”: The string “feed” is not a registered keyword.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “main” role is unnecessary for element “main”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
