本文实例讲述了jQuery实现的淡入淡出图片轮播效果。分享给大家供大家参考，具体如下：

1.HTML 框架搭建（css代码里宽高的大小与图片的大小一致）

css部分：

<style>
  * {
    padding: 0;
    margin:0;
  }
  ul {
    list-style: none;
  }
  .out {
    width: 640px;
    height: 270px;
    margin:50px auto;
    position: relative;
  }
  .out img{
    width: 640px;
    height: 270px;
  }
  .out .img li {
    position: absolute;
    left:0;
    top:0;
    display: none;
  }
  .out .num {
    position: absolute;
    bottom: 20px;
    left: 0;
    font-size:0px;
    text-align:center;
    width: 100%;
  }
  .out .num li {
    width: 20px;
    height: 20px;
    line-height:20px;
    border-radius:50%;
    background:#666;
    color: #fff;
    text-align:center;
    display: inline-block;
    font-size:16px;
    margin:0 3px;
    cursor: pointer;
  }
  .out .num li.active {
    background:#a00;
  }
  .out .btn {
    position:absolute;
    top: 50%;
    margin-top:-30px;
    width: 30px;
    height: 60px;
    line-height:60px;
    background:rgba(0, 0, 0, 0.5);
    font-size:40px;
    color: #fff;
    text-align:center;
    display: none;
  }
  .out .left {
    left: 0;
  }
  .out .right {
    right: 0;
  }
  .out:hover .btn {
    display: block;
    cursor: pointer;
  }
</style>

HTML部分：

<body>
  <div class="out ">
    <ul class="img ">
      <li>
        <a href="# " rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
          <img src="/UploadFiles/2021-04-02/1.jpg ">
