HTML markup errors and warnings
(Rescan now...)
Errors:
A “charset” attribute on a “meta” element found after the first 1024 bytes.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
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 “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Bad value “720; URL=” for attribute “content” on element “meta”: Expected an IRI reference, but the literal ended.
Stray end tag “div”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “sizes” attribute may be specified only if the “srcset” attribute is also present.
The “font” element is obsolete. Use CSS instead.
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “_blank"” not allowed on element “a” at this point.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Attribute “_blank"” is not serializable as XML 1.0.
Empty heading.
