因为代码不多所以我就写一个html文件里了
<div class="banner"> <ul> <li><a href="javascript:;"><img src="./1 (1).png" /></a></li> <li><a href="javascript:;"><img src="./1 (2).png" /></a></li> <li><a href="javascript:;"><img src="./1 (3).png" /></a></li> <li><a href="javascript:;"><img src="./1 (4).png" /></a></li> <li><a href="javascript:;"><img src="./1 (5).png" /></a></li> </ul> <div class="arrow"> <span class="arrow-l"><</span> <span class="arrow-r">></span> </div> <ol> <li class="dot"></li> <li></li> <li></li> <li></li> <li></li> </ol> </div>
