IE中a标签的边框去掉

源码

<a href="#page2" class="animate-bounce-down">
  <img src="harrow.png" alt="" style="width: 100%;display: block">
</a>

解决方法：

/*箭头上下跳动*/
@-webkit-keyframes bounce-down {
  25% {-webkit-transform: translateY(-10px);}
  50%, 100% {-webkit-transform: translateY(0);}
  75% {-webkit-transform: translateY(10px);}
 }

 @keyframes bounce-down {
  25% {transform: translateY(-10px);}
  50%, 100% {transform: translateY(0);}
  75% {transform: translateY(10px);}
 }

 .animate-bounce-down{
     display: block;
     position: absolute;
     left: 50%;
     bottom: 20px;
     z-index: 996;
     width: 30px;
     height: 30px;
     -webkit-animation: bounce-down 2s linear infinite;
     animation: bounce-down 2s linear infinite;
 }
 .animate-bounce-down img {
     border: 0 none;
 }
