What is HTML <dl>tag?

This tag is specifically useful when you want to present a collection of terms and their associated definitions, making it a valuable tool in structuring content more effectively.

For instance, you can use the `class` attribute to style a `<dl>` element with CSS or the `id` attribute to target it in JavaScript. These attributes make`<dl>` more versatile, allowing developers to tailor its appearance and behavior while maintaining semantic markup for describing lists of terms and their definitions.
Can I nest other HTML tags within the HTML <dl>tag?

What happens if I omit the <dd>tag within an HTML <dl>tag?
