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, or else use a “div” element instead for any cases where no heading is needed\.
# Opinionated informational messages.
Self-closing tag syntax in text/html documents is widely discouraged; it’s unnecessary and interacts badly with other HTML features \(e\.g\., unquoted attribute values\)\. If you’re using a tool that injects self-closing tag syntax into all void elements, without any option to prevent it from doing so, then consider switching to a different tool\.
