Instead of hard-coding every single button in HTML, the project uses JavaScript to generate the grid dynamically. This keeps the HTML clean and makes adding new sounds as easy as updating the array.

  const btn = document.createElement('button');
  btn.innerText = sound.name;
  btn.onclick = () => playSound(sound.file);
  container.appendChild(btn);
);

At its core, a soundboard is a grid of buttons. Each button, when clicked, plays a specific audio file. While the concept is simple, a good implementation requires clean organization and thoughtful user feedback.

This project uses a single index.html file to keep things lightweight and portable. No external frameworks are required; just pure HTML, CSS, and JavaScript.
