What is the role of the details tag in HTML?

The details tag in HTML is designed to create a disclosure widget from which users can obtain additional information or details about a topic. When the details tag is used, it provides a mechanism for the user to toggle the visibility of the extra content. This functionality enhances user interaction by allowing them to click on a summary to reveal or hide more information without navigating away from the page or cluttering the layout.

By using the details tag along with the summary tag, developers can create a compact interface where users can choose what information they want to see. This is particularly useful for FAQs or sections of a webpage where long explanations can be provided but are not necessary for every user to see at all times.

In contrast, other tags mentioned, such as those for creating clickable areas or inserting line breaks, do not provide this interactive disclosure feature. The division section tag is used to group content but does not inherently allow for the visibility toggling that the details tag offers.
