wordpress美化：利用before选择器给网站Logo添加扫光特效

wordpress美化：利用before选择器给网站Logo添加扫光特效
方法很简单，只需要添加一段css代码即可，如果你是WordPress程序，那么请在当前主题css文件最下方添加如下代码，需注意：代码中的#logo:before，根据自己的实际情况修改为当前主题的Logo元素选择器名称。

/**logo扫光效果CSS**/
#logo:before{
    content:"";
    position: absolute;
    left: -665px;
    top: -460px;
    width: 200px;
    height: 15px;
    background-color: rgba(255,255,255,.5);
    -webkit-transform: rotate(-45deg);
    -moz-transform: rotate(-45deg);
    -ms-transform: rotate(-45deg);
    -o-transform: rotate(-45deg);
    transform: rotate(-45deg);
    -webkit-animation: searchLights 1s ease-in 1s infinite;
    -o-animation: searchLights 1s ease-in 1s infinite;
    animation: searchLights 1s ease-in 1s infinite;
}
@-webkit-keyframes searchLights {
    0% { left: -100px; top: 0; }
    to { left: 120px; top: 100px; }
}
@-o-keyframes searchLights {
    0% { left: -100px; top: 0; }
    to { left: 120px; top: 100px; }
}
@-moz-keyframes searchLights {
    0% { left: -100px; top: 0; }
    to { left: 120px; top: 100px; }
