整体效果

这个效果主要用 css3 的 animation 属性来实现的。

这个效果可以用作在网站的整体 Loading，也可以放在网站首屏当一个 banner 的背景也是非常棒的！

代码部分

html 部分代码：

<div class="app"><span class="red"></span><span class="green"></span><span class="blue"></span>
</div>

写出三个圆，class 分别为 .red、.green、.blue。

css 部分代码：

.app{width:100%;height: 100vh;display: flex;justify-content: center;align-items: center;
}
span{width: 60px;height: 60px;margin: 40px;border-radius: 50%;
}
.red{animation: just1 2s ease-in-out infinite alternate;
}
.green{animation: just2 3s ease-in-out infinite alternate;
}
.blue{animation: just3 4s ease-in-out infinite alternate;
}
@keyframes just1{0%{border: 5px solid rgba(255,0,0,0);box-shadow: 0 0 0 rgba(255,0,0,0),0 0 0 rgba(255,0,0,0) inset;}100%{border: 5px solid rgba(255,0,0,1);box-shadow: 0 0 70px rgba(255,0,0,0.7),0 0 15px rgba(255,0,0,0.5) inset;}
}
@keyframes just2{0%{border: 5px solid rgba(0,255,0,0);box-shadow: 0 0 0 rgba(0,255,0,0),0 0 0 rgba(0,255,0,0) inset;}100%{border: 5px solid rgba(0,255,0,1);box-shadow: 0 0 70px rgba(0,255,0,0.7),0 0 15px rgba(0,255,0,0.5) inset;}
}
@keyframes just3{0%{border: 5px solid rgba(0,0,255,0);box-shadow: 0 0 0 rgba(0,0,255,0),0 0 0 rgba(0,0,255,0) inset;}100%{border: 5px solid rgba(0,0,255,1);box-shadow: 0 0 70px rgba(0,0,255,0.7),0 0 15px rgba(0,0,255,0.5) inset;}
}

css 部分主要使用 animation 来实现边框及其阴影的大小变化，和其透明度的变化。

完整代码如下

html 页面：

<!DOCTYPE html>
