CSS加載特效

CSS加載特效

1. 以下是css樣式,可以打包成css文件

.sk-circle {
      margin: 40px auto;
      width: 40px;
      height: 40px;
      position: relative; }
      .sk-circle .sk-child {
        width: 100%;
        height: 100%;
        position: absolute;
        left: 0;
        top: 0; }
      .sk-circle .sk-child:before {
        content: '';
        display: block;
        margin: 0 auto;
        width: 15%;
        height: 15%;
        background-color: #333;
        border-radius: 100%;
        -webkit-animation: sk-circleBounceDelay 1.2s infinite ease-in-out both;
                animation: sk-circleBounceDelay 1.2s infinite ease-in-out both; }
      .sk-circle .sk-circle2 {
        -webkit-transform: rotate(30deg);
            -ms-transform: rotate(30deg);
                transform: rotate(30deg); }
      .sk-circle .sk-circle3 {
        -webkit-transform: rotate(60deg);
            -ms-transform: rotate(60deg);
                transform: rotate(60deg); }
      .sk-circle .sk-circle4 {
        -webkit-transform: rotate(90deg);
            -ms-transform: rotate(90deg);
                transform: rotate(90deg); }
      .sk-circle .sk-circle5 {
        -webkit-transform: rotate(120deg);
            -ms-transform: rotate(120deg);
                transform: rotate(120deg); }
      .sk-circle .sk-circle6 {
        -webkit-transform: rotate(150deg);
            -ms-transform: rotate(150deg);
                transform: rotate(150deg); }
      .sk-circle .sk-circle7 {
        -webkit-transform: rotate(180deg);
            -ms-transform: rotate(180deg);
                transform: rotate(180deg); }
      .sk-circle .sk-circle8 {
        -webkit-transform: rotate(210deg);
            -ms-transform: rotate(210deg);
                transform: rotate(210deg); }
      .sk-circle .sk-circle9 {
        -webkit-transform: rotate(240deg);
            -ms-transform: rotate(240deg);
                transform: rotate(240deg); }
      .sk-circle .sk-circle10 {
        -webkit-transform: rotate(270deg);
            -ms-transform: rotate(270deg);
                transform: rotate(270deg); }
      .sk-circle .sk-circle11 {
        -webkit-transform: rotate(300deg);
            -ms-transform: rotate(300deg);
                transform: rotate(300deg); }
      .sk-circle .sk-circle12 {
        -webkit-transform: rotate(330deg);
            -ms-transform: rotate(330deg);
                transform: rotate(330deg); }
      .sk-circle .sk-circle2:before {
        -webkit-animation-delay: -1.1s;
                animation-delay: -1.1s; }
      .sk-circle .sk-circle3:before {
        -webkit-animation-delay: -1s;
                animation-delay: -1s; }
      .sk-circle .sk-circle4:before {
        -webkit-animation-delay: -0.9s;
                animation-delay: -0.9s; }
      .sk-circle .sk-circle5:before {
        -webkit-animation-delay: -0.8s;
                animation-delay: -0.8s; }
      .sk-circle .sk-circle6:before {
        -webkit-animation-delay: -0.7s;
                animation-delay: -0.7s; }
      .sk-circle .sk-circle7:before {
        -webkit-animation-delay: -0.6s;
                animation-delay: -0.6s; }
      .sk-circle .sk-circle8:before {
        -webkit-animation-delay: -0.5s;
                animation-delay: -0.5s; }
      .sk-circle .sk-circle9:before {
        -webkit-animation-delay: -0.4s;
                animation-delay: -0.4s; }
      .sk-circle .sk-circle10:before {
        -webkit-animation-delay: -0.3s;
                animation-delay: -0.3s; }
      .sk-circle .sk-circle11:before {
        -webkit-animation-delay: -0.2s;
                animation-delay: -0.2s; }
      .sk-circle .sk-circle12:before {
        -webkit-animation-delay: -0.1s;
                animation-delay: -0.1s; }

    @-webkit-keyframes sk-circleBounceDelay {
      0%, 80%, 100% {
        -webkit-transform: scale(0);
                transform: scale(0); }
      40% {
        -webkit-transform: scale(1);
                transform: scale(1); } }

      @keyframes sk-circleBounceDelay {
      0%, 80%, 100% {
        -webkit-transform: scale(0);
                transform: scale(0); }
      40% {
        -webkit-transform: scale(1);
                transform: scale(1); } }

        .parent{
            width: 100px;
            height: 100px;
            border: 0px solid red;
            position: absolute;

            text-align: center;

            left:0;
            right:0;
            top: 0;
            bottom: 0;
            margin: auto;
     }

1. 使用方法，頁面寫入以下div（可放入一個jsp內使用導入的方式這樣代碼簡介更少）

 <div class="parent" style="display: none;">
        <div class="sk-circle">
            <div class="sk-circle1 sk-child"></div>
            <div class="sk-circle2 sk-child"></div>
            <div class="sk-circle3 sk-child"></div>
            <div class="sk-circle4 sk-child"></div>
            <div class="sk-circle5 sk-child"></div>
            <div class="sk-circle6 sk-child"></div>
            <div class="sk-circle7 sk-child"></div>
            <div class="sk-circle8 sk-child"></div>
            <div class="sk-circle9 sk-child"></div>
            <div class="sk-circle10 sk-child"></div>
            <div class="sk-circle11 sk-child"></div>
            <div class="sk-circle12 sk-child"></div>
        </div>
   </div>

3.js代碼

<script>
var flag=true;
 $(function(){
    if(flag){
        $(".parent").show();//顯示
        $(".parent").show();/隱藏
        //根據自己邏輯判斷或者隱藏，ajax內也可以使用
    }
}) ;
</script>
