    Optional closing tags like p, li, etc.

    It is also worth mentioning that several other tags besides those mentioned in the question don't need a closing tag: they just close automatically when something specified in the standard appears.

    For example:

    <body>
<p>abc
<p>def
</body>

    is equivalent to:

    <body>
<p>abc
</p>
<p>def
</p>
</body>

    because the p closes both at:

    • the start of another p
    • when the parent of the p closes

    This is specified at 12.1.2.4 "Optional tags" https://html.spec.whatwg.org/multipage/syntax.html#optional-tags but I don't think there's an actual name besides "an element with an optional closing tag".

    See also: P-end-tag (</p>) is not needed in HTML
