Frequently Asked Questions

This accordion is built entirely with plain HTML, CSS, and a small amount of vanilla JavaScript. There are no external libraries, frameworks, fonts, or network requests involved — everything needed to render and operate it lives inside this single file.

Each question is a real <button> element, so it is reachable and operable with the keyboard by default and works correctly with screen readers. The aria-expanded attribute communicates the open or closed state, and aria-controls links each button to the answer panel it manages.

Yes. Each item in this accordion is independent, so you may open and close any combination of answers without affecting the others. If you prefer single-open behavior, the script could be easily adjusted to close other panels whenever a new one opens.

No. The page makes no network calls of any kind: there are no external stylesheets, fonts, scripts, or images. You can open this single HTML file directly in a browser, even completely offline, and it will work exactly as intended.
