## 话不多，先上效果： ##

## 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： ##

**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>

**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。

**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%;
            }
        }

**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
