vue加载动画

在index.html页面写入动画效果（这样就所有页面都可以用了，不用没个页面都去加）

//HTMLM
<div id="Loading">
      <!-- 加载动画 -->
      <div class="loader-inner ball-beat">
        <div></div>
        <div></div>
        <div></div>
      </div>
    </div>

#Loading {
  top:50%;
  left:50%;
  position: absolute;
  -webkit-transform: translateY(-50%)  translateX(-50%);
  transform: translateY(-50%)  translateX(-50%);
  z-index:100;
}
@-webkit-keyframes ball-beat {
  50% {
    opacity: 0.2;
    -webkit-transform: scale(0.75);
    transform: scale(0.75); }

  100% {
    opacity: 1;
    -webkit-transform: scale(1);
    transform: scale(1); } }

@keyframes ball-beat {
  50% {
    opacity: 0.2;
    -webkit-transform: scale(0.75);
    transform: scale(0.75); }

  100% {
    opacity: 1;
    -webkit-transform: scale(1);
    transform: scale(1); } }

.ball-beat > div {
  background-color: #279fcf;
  width: 15px;
  height: 15px;
  border-radius: 100% !important;
  margin: 2px;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
  display: inline-block;
  -webkit-animation: ball-beat 0.7s 0s infinite linear;
  animation: ball-beat 0.7s 0s infinite linear; }
.ball-beat > div:nth-child(2n-1) {
  -webkit-animation-delay: 0.35s !important;
  animation-delay: 0.35s !important; }

在app.vue页面

created () {
document.body.removeChild(document.getElementById('Loading')) // 加载完成时删除动画
}

效果：
