Question

在我的页面上，我有一个动画图像，在页面忙于加载时运行。我设法让它在页面繁忙时显示，在页面不忙时停止显示。当这个进度图像运行时，我正在努力让页面灰显...我已经读过关于div叠加的内容，但是它没有用。我该怎么做呢？我是javascript的新手

这就是我所做的：

在我的asp.net中，我有以下内容：

<div class="loading" align="center">
  <div class="main">
    <div class="small1">
      <div class="small ball smallball1"></div>
      <div class="small ball smallball2"></div>
      <div class="small ball smallball3"></div>
      <div class="small ball smallball4"></div>
    </div>

    <div class="small2">
      <div class="small ball smallball5"></div>
      <div class="small ball smallball6"></div>
      <div class="small ball smallball7"></div>
      <div class="small ball smallball8"></div>
    </div>

    <div class="bigcon">
      <div class="big ball"></div>
    </div>
  </div>
</div>

我的javascript如下：

<script type="text/javascript">

function ShowProgress() {
    setTimeout(function () {
        var loading = $(".loading");
        loading.show();
        $('#overlay').css({ 
          'display': 'block', 
          opacity: 0.7, 
          'width': $(document).width(), 
          'height': $(document).height() 
        });

        $('body').css({'overflow':'hidden'});

        $('#loading').css({ 'display': 'block' }).click(function () {
          $(this).css('display', 'none'); 
          $('#screen').css('display', 'none') 
        });            
    }, 200);

    $('#main').dialog({ modal: true });
}

$('form').live("submit", function () {       
    ShowProgress();
});

</script>

我的CSS看起来像这样：

body {
  padding: 0px;
  height:100%;
  background-color:#EBEBEB;
  filter:alpha(opacity=70);
  opacity:0.7;
  background-color: #002031;
}

.main {
    background-color:#EBEBEB;
    filter:alpha(opacity=70);
    opacity:0.7;
}

.small2 {
  position: absolute;
  height: 100px;
  width: 100px;
  background-color: transparent;
  top: 50vh;
  left: 50%;
  transform: translate(-50%, -50%);
}

.small1 {
  position: absolute;
  height: 100px;
  width: 100px;
  top: 50vh;
  left: 50%;
  transform-origin: center;
  transform: translate(-50%, -50%) rotate(45deg);
  background-color: transparent;
}

.bigcon {
  position: absolute;
  height: 95px;
  width: 95px;
  top: 50vh;
  left: 50%;
  transform-origin: center;
  transform: translate(-50%, -50%) rotate(-45deg);
  background-color: transparent;
  animation: bigcon 2s infinite linear;
  animation-delay: 0.25s;
 }

.ball {
  border-radius: 50%;
  position: absolute;
}

 .small {
  width: 25px;
  height: 25px;
  animation: small 2s infinite ease;
  box-shadow: 0px 2px rgba(0,0,0,0.3);
  background-color: #46b9ff;
}

 .small:nth-child(1) {
   top: 0%;
   left: 0%;
 }
 .small:nth-child(2) {
   top: 0%;
   right: 0%;
 }

 .small:nth-child(3) {
   right: 0%;
   bottom: 0%;
 }

.small:nth-child(4) {
  bottom: 0%;
  left: 0%;
}

.big {
  width: 20px;
  height: 20px;
  border-radius: 15px;
  box-shadow:0px 0px 10px #54f7f8, 0px 0px 20px #54f7f8, 0px 0px 30px #54f7f8, 0px 0px 50px #54f7f8, 0px 0px 60px #54f7f8 ;
  z-index: 1;
  background-color: #54f7f8;
  animation: bigball 1s infinite linear;
}

.smallball1{
  animation-delay: -1.75s;
}
.smallball6{
  animation-delay: -1.5s;
}
.smallball2{
  animation-delay: -1.25s;
}
.smallball7{
  animation-delay: -1s;
}
.smallball3{
  animation-delay: -0.75s;
}
.smallball8{
  animation-delay: -0.5s;
}
.smallball4{
  animation-delay: -0.25s;
}
.smallball5{
  animation-delay: -0s;
}

@keyframes bigcon {
  0% {
    transform-origin: center;
    transform: translate(-50%, -50%) rotate(45deg);
  }
  100% {
    transform-origin: center;
    transform: translate(-50%, -50%) rotate(405deg);
  }
}

@keyframes small {
  0% {
    transform: scale(1);
    background-color: #46b9ff;
  }
  10% {
    transform: scale(1.3);
    background-color: #54f7f8;
  }
  15% {
    transform: scale(1);
  }
  25%{
    transform: scale(1);
    background-color: #46b9ff;
  }
  100%{
    transform: scale(1);
    background-color: #46b9ff;
  }
}

#loading
{
  font-family: Arial;
  font-size: 10pt;
  border: 0px ;
  display: none;
  background-color: White;
  z-index: 999;   
}

我做错了什么？任何帮助将不胜感激

试试这个：

<强> CSS

.main:before{
    position: absolute;
    content:"";
    width: 100%;
    background: #EBEBEB;
    height: 100%;
    left:0;
    z-index:-1;
