HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
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.
The first occurrence of ID “myModalLabel1” was here.
Errors:
A “charset” attribute on a “meta” element found after the first 1024 bytes.
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.
Bad value “text/html; utf-8” for attribute “content” on element “meta”: The legacy encoding declaration did not start with space characters or “charset=” after the semicolon. Found “u” instead.
A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
No “p” element in scope but a “p” end tag seen.
Element “div” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “myModalLabel1”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “itemprop” attribute was specified, but the element is not a property of any item.
