CSS可以做一些基本的動畫效果

利用@keyframes創造動畫效果
<!DOCTYPE html>
<html>
<head>
<style>
div {
width: 100px;
height: 100px;
/* background-color: red; */
position: relative;
animation: myfirst 5s linear 2s infinite alternate;
}
@keyframes myfirst {
0% {left:0px; top:0px; transform: rotate(0deg);}
25% {left:200px; top:0px; transform: rotate(10deg);}
50% {left:200px; top:200px; transform: rotate(0deg);}
75% {left:0px; top:200px; transform: rotate(-10deg);}
100% {left:0px; top:0px; transform: rotate(0deg);}
}
</style>
</head>

<h1>CSS Animation</h1>
<p>This example uses the shorthand animation property:</p>
<div><img src="ben.webp" alt="Ben Wepp" style="width: 200px; height: 200px;"></div>
</body>
</html>
利用圖片的x、y位置來創造移動效果
<!DOCTYPE html>
<html>
<style>
#container {
width: 400px;
height: 400px;
position: relative;
background: yellow;
}
#animate {
width: 200px;
height: 200px;
position: absolute;
/* background-color: red; */
}
</style>
<body>
<p><button onclick="myMove()">Click Me</button></p>
<div id ="container" onclick="myMove()>
<div id ="animate">
<img src="ben.webp" alt="Ben Wepp" style="width: 200px; height: 200px;">
</div>
</div>
<script>
function myMove() {
let id = null;
const elem = document.getElementById("animate");
let pos = 0;
clearInterval(id);
id = setInterval(frame, 5);
function frame() {
if (pos == (400-200)) {
clearInterval(id);
} else {
pos++;
elem.style.top = pos + "px";
elem.style.left = pos + "px";
}
}
}
</script>
</body>
</html>
參考Animation，改一下:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Anime.js 動畫範例</title>
<style>
body {
background: #222;
color: #fff;
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
margin: 0;
}
.large {
font-size: 3rem;
letter-spacing: 0.2em;
}
span {
display: inline-block;
margin: 0 0.1em;
}
</style>
</head>
<body>
<h2 class="large">
<span>輔</span>
<span>仁</span>
<span>大</span>
<span>學</span>
<span>資</span>
<span>訊</span>
<span>管</span>
<span>理</span>
<span>學</span>
<span>系</span>
</h2>
<script src="<https://cdn.jsdelivr.net/npm/animejs/lib/anime.iife.min.js>"></script>
<script>
const { animate } = anime;
animate('span', {
// Property keyframes
y: [
{ to: '-2.75rem', ease: 'outExpo', duration: 600 },
{ to: 0, ease: 'outBounce', duration: 800, delay: 100 }
],
// Property specific parameters
rotate: {
from: '-1turn',
delay: 0
},
delay: (_, i) => i * 50, // Function based value
ease: 'inOutCirc',
loopDelay: 1000,
loop: true
});
</script>
</body>
</html>
很炫吧~~
