Chemcollective.org HTML Check

HTML Validation Tool

Errors

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.

Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.

Bad value “more info” for attribute “id” on element “p”: An ID must not contain whitespace.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Warnings

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
