Overview

After two days of ARIA theory lessons on freeCodeCamp, the next workshop focused on building an accessible audio controller. The session began with a completed example, followed by a series of incremental steps to add markup and ARIA attributes.

Step‑by‑Step Guide

1. Boilerplate HTML

• A Play button.
• A containing two elements with id attributes that will later be referenced by ARIA.

3. Add the Volume Slider

4. Apply ARIA Attributes

Link the slider to the previously created “ elements using aria-labelledby.

5. Add a Mute Button
