Answer 2

The problem is that you are using flexbox in a summary tag, which is not a structural one. summary is used inside a details element. Consider using a proper semantic tag like article or section for this, and it will work.

Code Snippet:

summary,
article {
  display: flex;
}
p::before {
  content: "Paragraph.";
}
details > summary {
  display: block;
}

<summary>
  <p></p>
  <p></p>
  <p></p>
</summary>

<article>
  <p></p>
  <p></p>
  <p></p>
</article>
