本文主要介绍了html css 图片扫描仪,分享给大家,具体如下:
效果:
这样,有抖动的:
无抖动的:
实现:
1.定义一个盒子:- <body>
- <div class="tu"></div>
- </body>
复制代码 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;
- }
复制代码 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;
-
- }
复制代码 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;
- }
- }
复制代码 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。

- 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>
