Quick Note: Using details to create no-script accordions

Hat Tip to : CSS Tricks.

An accordion is a UX element to group related items like Frequently asked questions. Most libraries give you a way to create accordions. But there is an easier way to accomplish the same goal, use the details and summary elements.

The details element creates a disclosure widget where information is visible only in its “open” state. A summary or label can be provided using the <summary> element.

The companion summary element specifies a summary, caption, or legend for a <details> element’s disclosure box. Clicking the <summary> element toggles the state of the parent <details> element open and closed.

You also get keyboard navigation for free. Thanks to HTML!

The following HTML…

<h2>Frequently Asked Questions</h2>

<details>
  <summary>What is the population of New Orleans?</summary>
<p>Every year, I took a holiday. I went to Florence, this cafe
on the banks of the Arno. Every fine evening, I would sit there
and order a Fernet Branca. I had this fantasy, that I would look
across the tables and I would see you there with a wife maybe a
couple of kids. You wouldn't say anything to me, nor me to you.
But we would both know that you've made it, that you were happy.
I never wanted you to come back to Gotham. I always knew there
was nothing here for you except pain and tragedy and I wanted
something more for you than that. I still do.</p>
</details>

And this CSS code:

@import url('https://fonts.googleapis.com/css?family=Raleway:400,400i,700|Roboto:700');

details {
  margin: 1rem;
}
summary {
  font-family: 'Roboto', sans-serif;
}

p {
  text-indent: 1em;
  font-family: 'Raleway', sans-serif;
}

h2 {
  font-family: 'Roboto', sans-serif;
  font-size: 2.5em;
  font-weight: bold;
}
