Learn to develop native exclusive accordion details lists without JavaScript, and styling them to be nicer looking using CSS. Question 1: What is a "Native Accordion? It's a standard HTML details element that, when combined with the name attribute, gains mutually exclusive behavior. Question 2: Does this need JavaScript? Nope! The browser handles all the open/close logic and the grouping, making it extremely performant and accessible by default. Question 3: Why use it? It greatly simplifies FAQ pages, menus, or any list of content where you only want one section visible at a time.
