CSS實現圖標閃爍效果

.

.outDiv{
  width:30px;
  height:30px;
  display: flex;
  justify-content: center;
  align-items: center;
  .blingbling{
    border: 6px solid #73BF00;
    width: 36px;
    height: 36px;
    border-radius: 50%;
    position: absolute;
    -webkit-animation: scaleout 2.5s infinite ease-in-out;
    animation: scaleout 2.5s infinite ease-in-out;
  }
  @-webkit-keyframes scaleout {
    0% { -webkit-transform: scale(1.0) }
    100% {
      -webkit-transform: scale(1.1);
      opacity: 0;
    }
  }
  @keyframes scaleout {
    0% {
      transform: scale(1.0);
      -webkit-transform: scale(1.0);
    } 100% {
        transform: scale(1.1);
        -webkit-transform: scale(1.1);
        opacity: 0;
      }
  }
}

只要把這個樣式加到你的圖標<img>或<div>上，就有效果啦~

例如：

<div class="outDiv">
        <img src="../img/xinhao.png" />
        <div class="blingbling"></div>
      </div>

其中1.3s是閃爍的頻率，寬高自己調整，祝你開發愉快~
