An ID attribute does not conform with the HTML document type specification. ID tokens must begin with a letter, and may contain only letters, digits, hyphens, underscores, colons, and periods.
<li> ID "_note-0" uses XML ID syntax
![]() | <li id="_note-0">Note number zero.</li> |
![]() | <li id="note-0">Note number zero.</li> |
Choose another name for the ID.
