本文主要介绍了html css 图片扫描仪,分享给大家,具体如下: 实现: 1.定义一个盒子: <body> <div class="tu"></div> </body> 2.基本样式,长宽背景图等等~ .tu{ width: 500px; height: 300px; background-image: url(8.jpg); background-size: 100% auto; background-repeat: no-repeat; position: relative; overflow: hidden; cursor: pointer; } cursor: pointer;鼠标经过盒子样式为小手 3.用伪类元素做扫描线,基本样式: .tu::after{ content: ''; position: absolute; top: 0; left: 0; width: 500px; height: 35px; background-image: url(8.jpg); background-size: 100% auto; background-repeat: no-repeat; filter: sepia(100%); opacity: 0; } filter: sepia(100%); 图片发黄。 filter: invert(100%); 像X光底片。 4.实现扫描: .tu:hover::after{ opacity: 1; animation: move 1.8s linear infinite; } @keyframes move{ 0%{ top: 0; background-position: 6px 0px; } 20%{ top: 60px; background-position: -6px -60px; } 40%{ top: 120px; background-position: 6px -120px; } 60%{ top: 180px; background-position: -6px -180px; } 80%{ top: 240px; background-position: 6px -240px; } 100%{ top: 300px; background-position: -6px -300px; } } 让background-position的y轴位移刚好等于top的距离,然后x轴为0的话就不抖,有数值就会抖动。 完整代码: <!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> <style> *{ margin: 0; padding: 0; box-sizing: border-box; } body{ height: 100vh; display: flex; justify-content: center; align-items: center; background-color: rgb(0, 0, 0); } .tu{ width: 500px; height: 300px; background-image: url(8.jpg); background-size: 100% auto; background-repeat: no-repeat; position: relative; overflow: hidden; cursor: pointer; } .tu::after{ content: ''; position: absolute; top: 0; left: 0; width: 500px; height: 20px; background-image: url(8.jpg); background-size: 100% auto; background-repeat: no-repeat; filter: invert(100%); opacity: 0; } .tu:hover::after{ opacity: 1; animation: move 1.8s linear infinite; } @keyframes move{ 0%{ top: 0; background-position: 6px 0px; } 20%{ top: 60px; background-position: -6px -60px; } 40%{ top: 120px; background-position: 6px -120px; } 60%{ top: 180px; background-position: -6px -180px; } 80%{ top: 240px; background-position: 6px -240px; } 100%{ top: 300px; background-position: -6px -300px; } } </style> </head> <body> <div class="tu"></div> </body> </html> 总结: 这是网上看到一外国博主的创意,然后自己也弄了一个,虽然效果是比较简单的,但也是挺好玩的~ (编辑:聊城站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
