使用纯CSS制作钟表

HTML结构

创建一个基本的HTML结构，包含钟表的各个部分：表盘、时针、分针和秒针。

<div class="clock">
  <div class="clock-face">
    <div class="hand hour-hand"></div>
    <div class="hand min-hand"></div>
    <div class="hand sec-hand"></div>
  </div>
</div>

CSS样式

通过CSS实现钟表的外观和动画效果。

表盘样式

.clock {
  width: 300px;
  height: 300px;
  border-radius: 50%;
  background-color: #f0f0f0;
  position: relative;
  margin: 50px auto;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
}

.clock-face {
  width: 100%;
  height: 100%;
  position: relative;
}

指针样式

.hand {
  position: absolute;
  bottom: 50%;
  left: 50%;
  transform-origin: 50% 100%;
  background-color: #333;
}

.hour-hand {
  width: 6px;
  height: 80px;
  margin-left: -3px;
}

.min-hand {
  width: 4px;
  height: 120px;
  margin-left: -2px;
}

.sec-hand {
  width: 2px;
  height: 140px;
  margin-left: -1px;
  background-color: red;
}

动画效果 使用CSS动画实现指针的旋转。

.clock-face {
  animation: rotate 43200s infinite linear;
}

.hour-hand {
  animation: rotate 43200s infinite linear;
}

.min-hand {
  animation: rotate 3600s infinite linear;
}

.sec-hand {
  animation: rotate 60s infinite linear;
}

@keyframes rotate {
  100% {
    transform: rotate(360deg);
  }
}

刻度标记

为表盘添加刻度标记，增强视觉效果。

.clock-face::before {
  content: '';
  position: absolute;
  width: 12px;
  height: 12px;
  background-color: #333;
  border-radius: 50%;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  z-index: 10;
}

.clock-face::after {
  content: '';
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  border-radius: 50%;
  box-sizing: border-box;
  border: 2px solid #333;
}

刻度线

纯css制作钟表

.clock-face {
  background-image: 
    linear-gradient(0deg, transparent 50%, #333 50%),
    linear-gradient(30deg, transparent 50%, #333 50%),
    linear-gradient(60deg, transparent 50%, #333 50%),
    linear-gradient(90deg, transparent 50%, #333 50%),
    linear-gradient(120deg, transparent 50%, #333 50%),
    linear-gradient(150deg, transparent 50%, #333 50%),
    linear-gradient(180deg, transparent 50%, #333 50%),
    linear-gradient(210deg, transparent 50%, #333 50%),
    linear-gradient(240deg, transparent 50%, #333 50%),
    linear-gradient(270deg, transparent 50%, #333 50%),
    linear-gradient(300deg, transparent 50%, #333 50%),
    linear-gradient(330deg, transparent 50%, #333 50%);
  background-size: 100% 100%;
}
