STEP1: 整體HTML架構

STEP2: 用CSS繪製雲朵圖標

CSS代碼如下

body {

max-width: 42em;

padding: 2em;

margin: 0 auto;

color: #161616;

font-family: 'Roboto', sans-serif;

text-align: center;

background-color: currentColor;

}

{

position: relative;

display: inline-block;

width: 12em;

height: 10em;

font-size: 1em; /* control icon size here */

}

d {

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:

display: block;

width: 4.5625em;

height: 1em;

background: currentColor;

box-shadow: 0 0.4375em 0 -0.0625em #fff;

}

d:nth-child(2) {

2.0625em 0.9375em 0 -0.5625em #fff;

opacity: 0.3;

transform: scale(0.5) translate(6em, -3em);

animation: cloud 4s linear infinite;

}

d:nth-child(2):after { background: #fff; }

{

position: absolute;

z-index: 2;

-1.375em -0.125em 0 rgba(255,255,255,0.2);

transform: rotate(-28deg);

animation: rain 3s linear infinite; /*設置動畫 rain */

}

STEP3: 下雨動畫

/* 下雨動畫 Animations */

@keyframes rain {

0% {

background: #0cf;

box-shadow:

}

25% {

-1.375em -0.125em 0 rgba(255,255,255,0.2);

}

50% {

background: rgba(255,255,255,0.3);

box-shadow:
