css实现图片闪光效果

1.这个效果是看到京东商城上的一个下效果,原本的思路是

用js控制一个图片在某张需要闪光的图片上重复出现,但是

网上找了一些资料,竟然是用css写的,真是太帅了!!!

2.原理:在需要闪光的图片前添加before 属性;内容为空;

宽为200px,高为100%,left:-150px,overflow:hiddden;

background属性设置为渐变;颜色看自己需要;transform-skewX(-25deg)

然后为before的content设置过渡动画:{left:150%,transiton:150px 1s ease 0s}

就可以了;

3:参考代码如下:

 

img{width:800px;height:450px;margin:0 auto;}
.img { display:block; position: relative; width:800px; height:450px; margin:0 auto;}
.img:before{ content: ""; position: absolute; width:200px; height: 100%; top: 0; left: -150px; overflow: hidden;

 

background: -moz-linear-gradient(left, rgba(255,255,255,0)0, rgba(255,255,255,.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,.2)), color-stop(100%, rgba(255,255,255,0)));

 

background: -webkit-linear-gradient(left, rgba(255,255,255,0)0, rgba(255,255,255,.2)50%, rgba(255,255,255,0)100%);

 

background: -o-linear-gradient(left, rgba(255,255,255,0)0, rgba(255,255,255,.2)50%, rgba(255,255,255,0)100%);

 

-webkit-transform: skewX(-25deg);
-moz-transform: skewX(-25deg)

 

}

.img:hover:before { left: 150%; transition: left 1s ease 0s; }

 

<div>
<a href="#" class="img">
<img src="img/1.jpg" alt="风景"/>
</a>
</div>
