Even though it is a nice and handy tag, always be careful when to use it and what its true purpose is (to show a summary). Do not use it as a navigation, that could be a misuse of html tags.

Easy, look at this example

String in summary it can be like a link, well, you can just open it without a link)

This solution works as intended without any extra CSS, but the design is totally up to you. Add classes to the elements and style it up! If you’re curious about how I did it, I provided the link to the source code.

I did a post a few years ago and go into a little detail about styling, if you're interested.

Hello!
I have modified it a little to highlight it:

<details>
    <summary><h1><span style="color: #333399; background-color: #ffffff;"><strong>DETALLE DE CONTENIDOS:</strong></span></h1></summary>
<p>
   CONTENIDO CONTENIDO CONTENIDO
</p>
</details>

But then you need to write JavaScript which defeats the point of this article! 🥲

That's not exactly an accordion element.

The key point of "accordion" is you have a list of titles grouped together. Clicking on one title will expand it WHILE collapsing the rest of the titles in the group. Clicking on an expanded title simply collapse it.

The tag only represents a single title.

I thought the details tag was common knowledge but I'm surprised a lot of people don't know HTML5. I learned HTML5 back in 2014 and thought most people knew about it.

I think when you learn HTML you don’t sit down and memorise all the tags – there are a lot! Sometimes you don’t know something because you’ve never needed it. Just because you don’t know that a certain tag exists, doesn’t mean you don’t know HTML 😁

l learned HTML5 as a part of the I.T degree I was studying back then, we had to learn every tag, and even though I don't use the tag, I know it exists and what it does. You can't say you know HTML when you only know 10 tags either.

Opera seams to support. Maybe not mini but that's a different browser.
