HTML details: Main Tips

  • The HTML <details> element generates a disclosure widget. In it, information can be either shown or hidden from users.
  • A combination of <summary> and <details> HTML elements is frequently used.
  • The <details> tags accept various content.

Use of details

HTML <details> sets a disclosure widget seen as a small triangle which can be manipulated to show or hide information.

By default, HTML <details> is false, meaning that content is hidden automatically.

Example
<details>
  <summary>Copyright</summary>
  <p>- by your company</p>
  <p>Content governed by copyright.</p>
</details>

Note: the content of <summary> (if it is the first child) is the label for the disclosure widget the <details> tag HTML creates.

open

The open attribute makes contents of the <details> element visible. Internet Explorer and Microsoft Edge browsers do not support this attribute.

Example
<details open>
  <summary>Click here to hide or show</summary>
  <p>- Visible by default</p>
</details>
