css扫光效果总结

扫光效果包括：css文字扫光，css图片扫光

思路

其实扫光的思路都是一样的，不外乎是表层一个动态的光，从左往右进行一个动画运动！

但是这个运动的光，一般是用过伪元素来::after或者::before来实现的。

然后我们对这个伪元素用css的渐变gradient进行处理。

文字扫光

废话少说，我们接下来实现一个简单的扫光文字！

.sample{
    background-color: #0E1326;
    padding-top:30px;
    overflow: hidden;
  }
  .blank_text{
    position: relative;
    width:200px;
    margin:20px auto;
    color: #fff;
    line-height: 1;
    font-size: 50px;
    font-size: 0.74074rem;
    text-align: center;
    overflow: hidden;
    font-family: "icomoon";
  }
.blank_text:after{
    width: 300%;
    height: 100%;
    content: "";
    position: absolute;
    top: 0;
    left: 0;
    background: -webkit-gradient(linear, left top, right top, color-stop(0, rgba(15,20,40, 0.7)), color-stop(0.4, rgba(15,20,40, 0.7)), color-stop(0.5, rgba(15,20,40, 0)), color-stop(0.6, rgba(15,20,40, 0.7)), color-stop(1, rgba(15,20,40, 0.7)));
    -webkit-animation: slide ease-in-out 2s infinite; 
}
@-webkit-keyframes slide{
    0%{-webkit-transform:translateX(-66.666%);}
    100%{-webkit-transform:translateX(0);}

<div class="sample">
    <div class="blank_text">haorooms博客扫光测试</div>
</div>

预览效果如下：

<iframe style="width: 780px; height: 100px;" src="http://sandbox.runjs.cn/show/k5k3s0y2" frameborder="0"></iframe>

图片扫光

通过鼠标移上去，伪类位置发生变化，通过如下代码：

.banner-bg .banner-box .right-pic:hover::before {
  -webkit-transition: left .8s;
  -moz-transition: left .8s;
  transition: left .8s;
  left: 480px;
}

 位置发生改变。

我这里也简单的实现一下！

如下：

<iframe style="color: #444444; font-family: 'Microsoft Yahei', 'Trebuchet MS', Georgia, 'Times New Roman', Times, sans-serif; background-color: #fcfcfa; width: 780px; height: 180px;" src="http://sandbox.runjs.cn/show/gunlnisc" frameborder="0"></iframe>

@keyframes aniBlink {
from {
margin-left:-440px
}
to {
    margin-left:500px
}
}
@-webkit-keyframes aniBlink {
from {
margin-left:-440px
}
to {
    margin-left:500px
}
}
.logo {
    position:relative;
    width:440px;
    height:160px;
    overflow:hidden;
}
.logo a {
    display:inline-block
}
.logo a:before {
    content:'';
    position:absolute;
    width:60px;
    height:160px;
    margin-top:0px;
    margin-left:-440px;
    overflow:hidden;
    z-index:6;
  overflow: hidden;
  background: -moz-linear-gradient(left, rgba(255, 255, 255, 0) 0, rgba(255, 255, 255, 0.2) 50%, rgba(255, 255, 255, 0) 100%);
  background: -webkit-gradient(linear, left top, right top, color-stop(0%, rgba(255, 255, 255, 0)), color-stop(50%, rgba(255, 255, 255, 0.2)), color-stop(100%, rgba(255, 255, 255, 0)));
  background: -webkit-linear-gradient(left, rgba(255, 255, 255, 0) 0, rgba(255, 255, 255, 0.2) 50%, rgba(255, 255, 255, 0) 100%);
  background: -o-linear-gradient(left, rgba(255, 255, 255, 0) 0, rgba(255, 255, 255, 0.2) 50%, rgba(255, 255, 255, 0) 100%);
  -webkit-transform: skewX(-25deg);
  -moz-transform: skewX(-25deg);
}
.logo:hover a:before {
 -webkit-animation:aniBlink .8s ease-out forwards;
 -moz-animation:aniBlink .8s ease-out forwards;
 -o-animation:aniBlink .8s ease-out forwards;
 animation:aniBlink .8s ease-out forwards
}

<div class="logo">
    <a href="http://www.haorooms.com"><img src="http://sandbox.runjs.cn/uploads/rs/216/0y89gzo2/banner03.jpg" /></a>
</div>

当然我们也可以用那种位置偏移来做，都可以！
