CSS Bat 制作方法

制作一个CSS蝙蝠可以通过纯CSS代码实现，利用::before和::after伪元素结合边框和变换属性来绘制蝙蝠形状。以下是具体实现步骤：

HTML结构

<div class="bat"></div>

CSS样式

.bat {
  width: 100px;
  height: 50px;
  position: relative;
  margin: 50px auto;
}

.bat::before, .bat::after {
  content: "";
  position: absolute;
  width: 0;
  height: 0;
}

.bat::before {
  border-left: 50px solid transparent;
  border-right: 50px solid transparent;
  border-bottom: 80px solid #333;
  top: -80px;
  left: 0;
  transform: rotate(15deg);
}

.bat::after {
  border-left: 50px solid transparent;
  border-right: 50px solid transparent;
  border-bottom: 80px solid #333;
  top: -80px;
  right: 0;
  transform: rotate(-15deg);
}

动画效果增强

为蝙蝠添加翅膀扇动的动画效果，可以通过关键帧动画实现：

.bat::before {
  animation: flap-left 1s infinite alternate;
}

.bat::after {
  animation: flap-right 1s infinite alternate;
}

@keyframes flap-left {
  from { transform: rotate(15deg); }
  to { transform: rotate(45deg); }
}

@keyframes flap-right {
  from { transform: rotate(-15deg); }
  to { transform: rotate(-45deg); }
}

添加细节

完善蝙蝠的头部和身体部分，使整体更逼真：

.bat {
  background: #222;
  border-radius: 50% 50% 0 0;
}

.bat::before, .bat::after {
  border-bottom-color: #222;
  z-index: -1;
}

响应式调整

通过媒体查询适配不同屏幕尺寸：

@media (max-width: 600px) {
  .bat {
    width: 60px;
    height: 30px;
  }
  .bat::before, .bat::after {
    border-left-width: 30px;
    border-right-width: 30px;
    border-bottom-width: 50px;
    top: -50px;
  }
}

完整代码示例

整合后的完整CSS蝙蝠代码如下：

<!DOCTYPE html>
<html>
<head>
  <style>
    .bat {
      width: 100px;
      height: 50px;
      position: relative;
      margin: 100px auto;
      background: #222;
      border-radius: 50% 50% 0 0;
    }

    .bat::before, .bat::after {
      content: "";
      position: absolute;
      width: 0;
      height: 0;
      border-left: 50px solid transparent;
      border-right: 50px solid transparent;
      border-bottom: 80px solid #222;
      top: -80px;
      z-index: -1;
      animation-duration: 0.8s;
      animation-iteration-count: infinite;
      animation-direction: alternate;
    }

    .bat::before {
      left: 0;
      transform: rotate(15deg);
      animation-name: flap-left;
    }

    .bat::after {
      right: 0;
      transform: rotate(-15deg);
      animation-name: flap-right;
    }

    @keyframes flap-left {
      from { transform: rotate(15deg); }
      to { transform: rotate(45deg); }
    }

    @keyframes flap-right {
      from { transform: rotate(-15deg); }
      to { transform: rotate(-45deg); }
    }
  </style>
</head>
<body>
  <div class="bat"></div>
</body>
</html>
