HTML沒變

<link href="C1.css" rel="stylesheet" type="text/css">
<body>
	<a href="#">
		<svg><rect></rect></svg>
		按鈕
	</a>
</body>

CSS

*{
	margin: 0;
	padding: 0;
	box-sizing: border-box;
}

body{
	background: #FFFFFF;
	justify-content: center;
	align-items: center;
	min-height: 100vh;
	display: flex; 
}

a{
	position: absolute;
	top: 50%;
	left: 50%;
	transform: translate(-50%,-50%);
	width: 180px;
	height: 60px;
	text-align: center;
	line-height: 60px;
	font-family: sans-serif;
	text-transform: uppercase;
	font-size: 24px;
	letter-spacing: 2px;
	color: #000000;
	text-decoration: none; /*把底線拿掉，a標籤通常會帶有底線*/
	transition: 0.5s;
}

a svg,
a svg rect{
	position: absolute;
	top: 0;
	left: 0;
	width: 100%;
	height: 100%;
	fill: transparent; /*填充 透明*/
}

a svg rect{
	stroke: #101013; /*邊框*/
	stroke-width: 6;
	transition: 1.5s;
	stroke-dasharray: 480;
	stroke-dashoffset: 480;
}

a:hover svg rect
{
	stroke-dashoffset: 0;
}

a:hover /*描邊完後按鈕變色*/
{
	background: #8CC2FF;
	transition-delay: 1.5s;/* "描邊完" 的關鍵延遲*/
}

成果

今天先這樣，明天找別的
