// Execute when page is loaded
window.addEventListener('DOMContentLoaded', function() {
  // Example 1: Add click effect to all audio buttons
  const audioButtons = document.querySelectorAll('.playSound');
  audioButtons.forEach(button => {
    button.addEventListener('click', function() {
      // Add click animation effect
      this.style.transform = 'scale(0.95)';
      setTimeout(() => {
        this.style.transform = 'scale(1)';
      }, 100);
    });
  });

  // Example 2: Add new window opening functionality to all links
  const links = document.querySelectorAll('a');
  links.forEach(link => {
    link.setAttribute('target', '_blank');
    link.setAttribute('rel', 'noopener noreferrer');
  });

  // Example 3: Add custom toolbar
  const toolbar = document.createElement('div');
  toolbar.style.cssText = `
    position: fixed;
    top: 10px;
    right: 10px;
    background: rgba(255, 255, 255, 0.9);
    padding: 5px;
    border-radius: 5px;
    box-shadow: 0 2px 5px rgba(0,0,0,0.2);

    border: none;
    border-radius: 3px;
    background: #3498db;
    color: white;
    cursor: pointer;
  `;

  button.addEventListener('click', function() {
    document.body.classList.toggle('dark-theme');
  });

  toolbar.appendChild(button);
  document.body.appendChild(toolbar);
});

// Example 4: Define global function for other scripts to use
function highlightText(text) {
  const elements = document.querySelectorAll('p, span, div');
  elements.forEach(element => {
    if (element.textContent.includes(text)) {
      element.innerHTML = element.innerHTML.replace(
        new RegExp(text, 'gi'),
