哪位大佬可以教教写一个图片无线轮播

框架这么多，为啥要自己写

<div class="box"><ul class="banner_box"><li><img src="https://img1.360buyimg.com/pop/jfs/t28759/117/904598948/99412/a79bd8f2/5c015b00N0162f17a.jpg"alt=""><h2>这个似乎标题1</h2></li><!-- <li> <img src="https://img1.360buyimg.com/pop/jfs/t28759/117/904598948/99412/a79bd8f2/5c015b00N0162f17a.jpg" alt=""> <h2>这个似乎标题2</h2> </li> <li> <img src="https://img1.360buyimg.com/pop/jfs/t28759/117/904598948/99412/a79bd8f2/5c015b00N0162f17a.jpg" alt=""> <h2>这个似乎标题3</h2> </li> <li> <img src="https://img1.360buyimg.com/pop/jfs/t28759/117/904598948/99412/a79bd8f2/5c015b00N0162f17a.jpg" alt=""> <h2>这个似乎标题4</h2> </li> --></ul><div class="left_btn">< </div> <div class="right_btn"> ></div><ul class="tip_box"><li class="tip"></li></ul></div>
