<div class="accordion">
  <div class="accordion-item">
    <div class="accordion-header">标题1</div>
    <div class="accordion-content">内容1</div>
  </div>
  <div class="accordion-item">
    <div class="accordion-header">标题2</div>
    <div class="accordion-content">内容2</div>
  </div>
  <div class="accordion-item">
    <div class="accordion-header">标题3</div>
    <div class="accordion-content">内容3</div>
  </div>
</div>

.accordion {
  width: 100%;
}

.accordion-item {
  border: 1px solid #ccc;
  margin-bottom: 10px;
}

.accordion-header {
  background-color: #f0f0f0;
  padding: 10px;
  cursor: pointer;
}

.accordion-content {
  display: none;
  padding: 10px;
}

const accordionItems = document.querySelectorAll('.accordion-item');

accordionItems.forEach(item => {
  const header = item.querySelector('.accordion-header');
  const content = item.querySelector('.accordion-content');

  header.addEventListener('click', () => {
    content.style.display = content.style.display === 'none' ? 'block' : 'none';
  });
});
