The <details> and <summary> Elements in HTML5 are important for creating collapsible content sections. The <details> element acts as a container for content that can be hidden or revealed, and the <summary> provides a visible heading or label for the collapsible section.

When users click on the <summary> heading, it toggles the visibility of the content within the <details> element, offering a simple and interactive way to organize and present information on a webpage.
