Inside <details> we can see the <summary> at first.

If we click on the arrow, we see the hidden content!

Using the open attribute on <details> (open takes no additional value) will set the list to be open and visible by default, making it closable rather than openable. Together, <details> and <summary> construct what is known in web development as a “disclosure widget.”

<dfn>

This tag marks up the defining instance of a term, which is a specialized word that makes its first appearance in a document. The style of text enclosed within <dfn > defaults to italicized.

<p>In audio, <dfn>white noise </dfn>refers to a random signal comprised of all the audible frequencies played at equal loudness.</p>
