Simple FAQ Accordion

This is a simple FAQ accordion built with HTML, CSS, and vanilla JavaScript. It has a clean look and feel and also has icons to indicate if the accordion is collapsed or expanded.

The only limitation is that you can expand only one accordion at a time. But if you want to expand multiple accordions at the same time, you can remove the JavaScript code from lines 13-18.
