使用此svg，我尝试制作一个像梯子一样下降的动画。您如何使用CSS实现它？

我是初学者...

您可以使用SVG代替多边形来简化path，并在stroke-dasharray属性上运行CSS动画

svg {
   stroke: #ffe033;
   stroke-width: 10px;
   fill: none;
   width: 190px;
   height: 115px;
   stroke-dasharray: 0 660;
   animation: stroke 5s linear 0s 1 forwards;
} 

@keyframes stroke {
   to { stroke-dasharray: 660 660; }
}

<svg xmlns="http://www.w3.org/2000/svg" 
     xmlns:xlink="http://www.w3.org/1999/xlink" 
     viewBox="0 0 190 115">

     <path d="M5 0v30H185v30H5v30H185v30" />
</svg>
