前言

秋千一种运动和游戏的用具，在木架或铁架之间系上绳索，下面拴一块长板。人在板上用力蹬以来回摆动。

实现

布局

<div class="wrapper">
  <div class="swing">
	  <!-- 荡的部分 -->
    <div class="human">
		<!-- 上半部分 -->
      <div class="top-part">
        <div class="head">
			<!-- 头 -->
          <div class="hair"></div>
		  <!-- 头发 -->
          <div class="fringe"></div>
		  <!-- 刘海 -->
          <div class="eye"></div>
		  <!-- 眼睛 -->
          <div class="mouth"></div>
		  <!-- 嘴巴 -->
        </div>
        <div class="body">
			<!-- 身体 -->
          <div class="hand">
			  <!-- 手 -->
            <div class="hand-one"></div>
            <div class="hand-two"></div>
          </div>
        </div>
      </div>
      <div class="leg-one"></div>
	  <!-- 脚 -->
      <div class="leg-two"></div>
    </div>
    <div class="swing-rod"></div>
	<!-- 绳索 -->
    <div class="bottom"></div>
	<!-- 木板 -->
  </div>
  <div class="pole one"></div>
  <!-- 支撑物 -->
  <div class="pole two"></div>
</div>

样式

支撑物，众所周知建房子需要打好地基，不然房子容易坍塌，那么秋千也是如此。

.wrapper .pole {
  position: absolute;
  width: 5px;
  height: 250px;
  left: 50%;
  -webkit-transform-origin: center top;
          transform-origin: center top;
  -webkit-transform: translateX(-50%) rotate(-25deg);
          transform: translateX(-50%) rotate(-25deg);
  color: silver;
  background: currentColor;
}
.wrapper .pole.two {
  -webkit-transform: translateX(-50%) rotateY(-180deg) rotate(-25deg);
          transform: translateX(-50%) rotateY(-180deg) rotate(-25deg);
}
.wrapper .pole:before {
  content: "";
  position: absolute;
  top: -10px;
  left: -7px;
  width: 20px;
  height: 20px;
  border-radius: 100%;
  background: currentColor;
}
.wrapper .pole:after {
  content: "";
  position: absolute;
  left: 0;
  bottom: 0;
  width: 20px;
  height: 5px;
  -webkit-transform: translateX(-50%) rotate(25deg);
          transform: translateX(-50%) rotate(25deg);
  background: currentColor;
}

绳索和木板样式 连接上下部分就组合成了一个秋千

.wrapper .swing .swing-rod {
  position: absolute;
  width: 5px;
  height: 200px;
  left: 50%;
  -webkit-transform: translateX(-50%);
          transform: translateX(-50%);
  background: #323232;
}
.wrapper .swing .bottom {
  position: absolute;
  width: 100%;
  height: 5px;
  bottom: 0;
  background: saddlebrown;
}

  from {
    -webkit-transform: rotate(-35deg);
            transform: rotate(-35deg);
  }
  to {
    -webkit-transform: rotate(35deg);
            transform: rotate(35deg);
  }
}

@keyframes swing-1 {
  from {
    -webkit-transform: rotate(-35deg);
            transform: rotate(-35deg);
  }
  to {
    -webkit-transform: rotate(35deg);
            transform: rotate(35deg);
  }
}
@-webkit-keyframes body-animation {
  from {
    -webkit-transform: rotate(-25deg);
            transform: rotate(-25deg);
  }
  to {
    -webkit-transform: rotate(20deg);
            transform: rotate(20deg);
  }
}
@keyframes body-animation {
  from {
    -webkit-transform: rotate(-25deg);
            transform: rotate(-25deg);
  }
  to {
    -webkit-transform: rotate(20deg);
            transform: rotate(20deg);
  }
}
@-webkit-keyframes leg-animation {
  from {
    bottom: 2px;
    right: -8px;
    -webkit-transform: rotate(-55deg);
            transform: rotate(-55deg);
  }
  to {
    bottom: 2px;
    right: 5px;
    -webkit-transform: rotate(-170deg);
            transform: rotate(-170deg);
  }
}
@keyframes leg-animation {
  from {
    bottom: 2px;
    right: -8px;
    -webkit-transform: rotate(-55deg);
            transform: rotate(-55deg);
  }
  to {
    bottom: 2px;
    right: 5px;
    -webkit-transform: rotate(-170deg);
            transform: rotate(-170deg);
  }
}

总结

整篇主要用到的是css的transform属性的平移,@keyframes动画的旋转,绝对定位,背景颜色,堆叠顺序,阴影,边框,以上这些内容组合成的荡秋千的女孩,谢谢观看!
