HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “banner” role is unnecessary for element “header”.
The “contentinfo” role is unnecessary for element “footer”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “type” attribute is unnecessary for JavaScript resources.
Errors:
Attribute “type” not allowed on element “form” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
When the “srcset” attribute has any image candidate string with a width descriptor, the “sizes” attribute must also be present.
Bad value “x-template” for attribute “type” on element “script”: Subtype missing.
Start tag “a” seen but an element of the same type was already open.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “p” seen, but there were open elements.
Unclosed element “a”.
