HTML markup errors and warnings

(Rescan now...)

Errors:

Bad value “/administration/events/past/?search="Communicating+Astronomy+with+the+Public"” for attribute “href” on element “a”: Illegal character in query: “"” is not allowed.

“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.

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

Warnings:

The “form” role is unnecessary for element “form”.

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
