下面我们来做一个会下雨的天气图标实例，过程其实很简单哦。

让ICON生动起来纯CSS实现带动画的天气图标

STEP1: 整体HTML架构

<div class="icon rainy"> <div class="cloud"></div> <div class="rain"></div> </div>

STEP2: 用CSS绘制云朵图标

CSS代码如下

body { max-width: 42em; padding: 2em; margin: 0 auto; color: #161616; font-family: 'Roboto', sans-serif; text-align: center; background-color: currentColor; }  .icon { position: relative; display: inline-block; width: 12em; height: 10em; font-size: 1em; /* control icon size here */ }  .cloud { position: absolute; z-index: 1; top: 50%; left: 50%; width: 3.6875em; height: 3.6875em; margin: -1.84375em; background: currentColor; border-radius: 50%; box-shadow: -2.1875em 0.6875em 0 -0.6875em, 2.0625em 0.9375em 0 -0.9375em, 0 0 0 0.375em #fff, -2.1875em 0.6875em 0 -0.3125em #fff, 2.0625em 0.9375em 0 -0.5625em #fff; } .cloud:after { content: ''; position: absolute; bottom: 0; left: -0.5em; display: block; width: 4.5625em; height: 1em; background: currentColor; box-shadow: 0 0.4375em 0 -0.0625em #fff; } .cloud:nth-child(2) { z-index: 0; background: #fff; box-shadow: -2.1875em 0.6875em 0 -0.6875em #fff, 2.0625em 0.9375em 0 -0.9375em #fff, 0 0 0 0.375em #fff, -2.1875em 0.6875em 0 -0.3125em #fff, 2.0625em 0.9375em 0 -0.5625em #fff; opacity: 0.3; transform: scale(0.5) translate(6em, -3em); animation: cloud 4s linear infinite; } .cloud:nth-child(2):after { background: #fff; }  .rain{ position: absolute; z-index: 2; top: 50%; left: 50%; width: 3.75em; height: 3.75em; margin: 0.375em 0 0 -2em; background: currentColor; }  .rain:after { content: ''; position: absolute; z-index: 2; top: 50%; left: 50%; width: 1.125em; height: 1.125em; margin: -1em 0 0 -0.25em; background: #0cf; border-radius: 100% 0 60% 50% / 60% 0 100% 50%; box-shadow: 0.625em 0.875em 0 -0.125em rgba(255,255,255,0.2), -0.875em 1.125em 0 -0.125em rgba(255,255,255,0.2), -1.375em -0.125em 0 rgba(255,255,255,0.2); transform: rotate(-28deg); animation: rain 3s linear infinite; /*设置动画 rain */ }

STEP3: 下雨动画

/* 下雨动画 Animations */  @keyframes rain { 0% { background: #0cf; box-shadow: 0.625em 0.875em 0 -0.125em rgba(255,255,255,0.2), -0.875em 1.125em 0 -0.125em rgba(255,255,255,0.2), -1.375em -0.125em 0 #0cf; } 25% { box-shadow: 0.625em 0.875em 0 -0.125em rgba(255,255,255,0.2), -0.875em 1.125em 0 -0.125em #0cf, -1.375em -0.125em 0 rgba(255,255,255,0.2); } 50% { background: rgba(255,255,255,0.3); box-shadow: 0.625em 0.875em 0 -0.125em #0cf, -0.875em 1.125em 0 -0.125em rgba(255,255,255,0.2), -1.375em -0.125em 0 rgba(255,255,255,0.2); } 100% { box-shadow: 0.625em 0.875em 0 -0.125em rgba(255,255,255,0.2), -0.875em 1.125em 0 -0.125em rgba(255,255,255,0.2), -1.375em -0.125em 0 #0cf; } }
