定義 dom,頁面中包含 2 個元素,分別表明兔子和雲朵:flex
<div class="rabbit"></div> <div class="clouds"></div>
居中顯示:動畫
body { margin: 0; height: 100vh; display: flex; align-items: center; justify-content: center; background: linear-gradient(midnightblue, black); font-size: 30px; }
畫出兔子的身體:spa
.rabbit { width: 5em; height: 3em; color: whitesmoke; background: currentColor; border-radius: 70% 90% 60% 50%; }
用徑向漸變畫出兔子的眼睛:
.rabbit { background: radial-gradient( circle at 4.2em 1.4em, #333 0.15em, transparent 0.15em ), /* eye */ currentColor; }
用僞元素畫出兔子的右耳:
.rabbit::before { content: ''; position: absolute; width: 0.75em; height: 2em; background-color: currentColor; border-radius: 50% 100% 0 0; transform: rotate(-30deg); top: -1em; right: 1em; }
用陰影畫出兔子的左耳:
.rabbit::before { border: 0.1em solid; border-color: gainsboro transparent transparent gainsboro; box-shadow: -0.5em 0 0 -0.1em; }
用僞元素畫出兔子的尾巴:
.rabbit::after { content: ''; position: absolute; width: 1em; height: 1em; background-color: currentColor; border-radius: 50%; left: -0.3em; top: 0.5em; }
用陰影畫出兔子的腿:
.rabbit::after { box-shadow: 0.5em 1em 0, 4em 1em 0 -0.2em, 4em 1em 0 -0.2em; }
畫出兔子的影子:
.rabbit { box-shadow: -0.2em 1em 0 -0.75em #333; }
畫出一個雲朵:
.clouds { width: 2em; height: 2em; color: whitesmoke; background: currentColor; border-radius: 100% 100% 0 0; transform: translate(0, -5em); } .clouds::before, .clouds::after { content: ''; position: absolute; background-color: currentColor; bottom: 0; } .clouds::before { width: 1.25em; height: 1.25em; border-radius: 100% 100% 0 100%; left: -30%; } .clouds::after { width: 1.5em; height: 1.5em; border-radius: 100% 100% 100% 0; right: -30%; }
用陰影再畫 2 個雲朵:
.rabbit { z-index: 1; } .clouds, .clouds::before, .clouds::after { box-shadow: 5em 2em 0 -0.3em, -2em 2em 0 0; }
接下來製做動畫效果。
增長兔子跳動的動畫:
.rabbit { animation: hop 3s linear infinite; } @keyframes hop { 20% { transform: rotate(-10deg) translate(1em, -2em); box-shadow: -0.2em 1em 0 -1em #333; } 40% { transform: rotate(10deg) translate(3em, -4em); box-shadow: -0.2em 3.25em 0 -1.1em #333; } 60%, 75% { transform: rotate(0deg) translate(4em, 0); box-shadow: -0.2em 1em 0 -0.75em #333; } }
增長兔子的腿的伸縮動畫:
.rabbit::after { animation: kick 3s infinite linear; } @keyframes kick { 40% { box-shadow: 0.5em 2em 0, 4.2em 1.75em 0 -0.2em, 4.4em 1.9em 0 -0.2em; } }
增長雲朵飄動的動畫:
.clouds { animation: cloudy 3s infinite linear forwards; filter: opacity(0); } @keyframes cloudy { 40% { transform: translate(-3em, -5em); filter: opacity(0.75); } 55% { transform: translate(-4em, -5em); filter: opacity(0); } }
大功告成!
