HTML markup errors and warnings
(Rescan now...)
Warnings:
Using “windows-1252” instead of the declared encoding “iso-8859-1”.
Consider avoiding viewport values that prevent users from resizing documents.
The “charset” attribute on the “script” element is obsolete.
The “type” attribute is unnecessary for JavaScript resources.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Errors:
Legacy encoding “windows-1252” used. Documents must use UTF-8.
Bad value “text/html; charset=ISO-8859-1” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
The only allowed value for the “charset” attribute for the “script” element is “utf-8”. (But the attribute is not needed and should be omitted altogether.)
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “cnec” not allowed on element “select” at this point.
Attribute “type” not allowed on element “textarea” at this point.
Attribute “cnec” not allowed on element “textarea” at this point.
Attribute “cnec” not allowed on element “input” at this point.
