HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “P3P” for attribute “http-equiv” on element “meta”.
Bad value “https://fonts.googleapis.com/css?family=Open+Sans|Open+Sans:700” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Attribute “ontouchstart” not allowed on element “body” 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.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
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).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in English but the “html” start tag has an empty “lang” attribute. Consider using “lang="en"” (or variant) instead.
