该效果的主要实现思路是给文字添加渐变的背景，然后对背景进行裁剪，按文字裁剪（目前只有webkit内核浏览器支持该属性），最后给背景添加动画，即改变背景的位置，背景动画效果如下（GIF录制时有卡顿，代码实现时不卡）：

最终效果：

全部代码如下：

<!DOCTYPE html><html><head>    <style>        p{            width:50%;            margin:0 auto;            line-height:50px;             font-size:50px;             text-align:center;                        -webkit-background-clip: text;    /*按文字裁剪*/                    -webkit-text-fill-color: transparent;    /*文字的颜色使用背景色*/                            background-color:#19385c;    /*设置一个背景色*/                    background-image: -webkit-linear-gradient(-45deg, rgba(0, 0, 0, 0.6) 30%, #aff0ff 50%, rgba(0, 0, 0, 0.6) 70%);        /*设置渐变的背景，按对角线渐变*/                        background-blend-mode: hard-light;    /*设置背景为混合模式下的强光模式*/            background-size: 200%;                        -webkit-animation: shine 4s infinite;    /*给背景添加动画改变位置*/        }        @-webkit-keyframes shine {          from {background-position: 100%;}          to {background-position: 0;}        }    </style></head><body><p>> Slide To Unlock</p></body></html>

需要说明的是由于按文字裁剪目前只有 webkit 内核可用，所以该效果目前不兼容其他内核浏览器。
