如何将3个滑块的自动播放分别延迟0.5秒？

// HTML结构示例
<div class="slider">
  <div class="slide">Slide 1</div>
  <div class="slide">Slide 2</div>
  <div class="slide">Slide 3</div>
</div>

// CSS样式示例
.slider {
  width: 300px;
  height: 200px;
  overflow: hidden;
}

.slide {
  width: 100%;
  height: 100%;
  display: none;
}

// JavaScript代码示例
window.addEventListener('load', function() {
  var slides = document.querySelectorAll('.slide');
  var currentIndex = 0;

  function playSlide() {
    slides[currentIndex].style.display = 'none';
    currentIndex = (currentIndex + 1) % slides.length;
    slides[currentIndex].style.display = 'block';
    setTimeout(playSlide, 500); // 延迟0.5秒后继续播放下一个滑块
  }

  playSlide(); // 启动滑块的自动播放
});
