Chem21.info W3C HTML Markup Validation

HTML markup errors and warnings

(Rescan now...)

Errors:

Start tag “head” seen but an element of the same type was already open.

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.

Element “index” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)

No “p” element in scope but a “p” end tag seen.

Warnings:

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).

Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
