炫彩按钮源码分析
简介：
用基础css做一个有一点炫酷的流光按钮，不止按钮，只要是盒子就行。
具体步骤：
button按钮源码
1.先定义一个盒子当做按钮，如我就用a标签：
<body>
<a href="#" class="guang">button</a>
</body>
a标签CSS
2.先给a标签写基础的样式，比如长宽等等…：
.guang{ position: relative; display: inline-block; width: 220px; height: 80px; color: rgb(255, 255, 255); line-height: 80px; font-size: 35px; font-family: sans-serif; text-decoration: none; text-transform: uppercase; text-align: center; border-radius: 30px; background: linear-gradient(90deg,rgb(39, 122, 218),rgb(74, 230, 121),rgb(201, 214, 13),rgb(226, 20, 233),rgb(16, 172, 219)); background-size: 400%; z-index: 1; text-shadow: 0 0 5px white, 0 0 5px white; }
注意：其中一些属性用处：
text-transform: uppercase; 全部换成大写字母。
background: linear-gradient(…); 线性颜色渐变，可以改成自己要的颜色。
text-shadow: 0 0 5px white,
0 0 5px white;
写两行是为了让字体更亮。
鼠标悬浮
3.鼠标经过盒子产生流光的动画：
.guang:hover{ animation: move 5s linear alternate infinite; } @keyframes move{ 0%{ background-position: 0%; } 100%{ background-position: 100%; } }
阴影样式
4.定义盒子周围的光晕阴影：
.guang::before{ content: ''; position: absolute; top: -10px; left: -10px; width: 240px; height: 100px; background: linear-gradient(90deg,rgb(39, 122, 218),rgb(74, 230, 121),rgb(243, 169, 10),rgb(226, 20, 233),rgb(16, 172, 219)); background-size: 400%; opacity: 0; z-index: -1; border-radius: 45px; transition: 0.6s; } .guang:hover::before{ filter: blur(15px); opacity: 1; animation: move 8s linear alternate infinite; }
注意：其中一些属性用处：
filter: blur 滤镜，就是让其模糊
