【问题描述】：
正如标题所暗示的，我正在尝试创建一个动画，在我创建的按钮周围绘制一个无限线循环，但由于某种原因它没有呈现。下面是我的 CSS 和 HTML 代码。
<!DOCTYPE HTML>
<head>
<link rel="stylesheet" href="style.css">
</head>
<div class="pathway-box">
<body>
<h2>Which Person Are You Looking For?</h2>
<form>
<a href ="/home/chimera/Documents/k13c/fail/jr/index.html" class="Jr">Jr</a>
<a href="#" class="Sr">Sr</a>
</form>
</div>
</body>
@import url('https://fonts.googleapis.com/css2?family=Quicksand:wght@700&display=swap');
html {
height: 100%;
}
body {
margin:0;
padding:0;
font-family: sans-serif;
background: rgb(2,0,36);
background: linear-gradient(90deg, rgba(2,0,36,1) 0%, rgba(22,22,85,1) 19%, rgba(0,212,255,1) 100%);
}
.pathway-box {
position: absolute;
top: 50%;
left: 50%;
width: 400px;
padding: 40px;
transform: translate(-50%, -50%);
background: rgba(0,0,0,.5);
box-sizing: border-box;
box-shadow: 0 15px 25px rgba(0,0,0,.6);
border-radius: 10px;
}
.pathway-box h2 {
margin: 0 0 30px;
padding: 0;
color: #fff;
font-family: 'Quicksand', sans-serif;
text-align: center;
margin: 40px;
}
.pathway-box .user-box input:focus ~ label,
.pathway-box .user-box input:valid ~ label {
top: -20px;
left: 0;
color: #03e9f4;
font-size: 12px;
}
.pathway-box form a {
font-family: 'Quicksand', sans-serif;
position: relative;
display: inline-block;
padding: 10px 20px;
color: #03e9f4;
font-size: 16px;
text-decoration: none;
overflow: hidden;
transition: .5s;
margin-top: 40px;
letter-spacing: 4px
}
.pathway-box a:hover {
background: #03e9f4;
color: #fff;
border-radius: 5px;
box-shadow: 0 0 5px #03e9f4,
0 0 25px #03e9f4,
0 0 50px #03e9f4,
0 0 100px #03e9f4;
}
.pathway-box a span {
position: absolute;
display: block;
}
.pathway-box a span:nth-child(1) {
top: 0;
left: -100%;
width: 100%;
height: 2px;
background: linear-gradient(90deg, transparent, #03e9f4);
animation: btn-anim1 1s linear infinite;
}
@keyframes btn-anim1 {
0% {
left: -100%;
}
50%,100% {
left: 100%;
}
}
.pathway-box a span:nth-child(2) {
top: -100%;
right: 0;
width: 2px;
height: 100%;
background: linear-gradient(180deg, transparent, #03e9f4);
animation: btn-anim2 1s linear infinite;
animation-delay: .25s
}
@keyframes btn-anim2 {
0% {
top: -100%;
}
50%,100% {
top: 100%;
}
}
.pathway-box a span:nth-child(3) {
bottom: 0;
right: -100%;
width: 100%;
height: 2px;
background: linear-gradient(270deg, transparent, #03e9f4);
animation: btn-anim3 1s linear infinite;
animation-delay: .5s
}
@keyframes btn-anim3 {
0% {
right: -100%;
}
50%,100% {
right: 100%;
}
}
.pathway-box a span:nth-child(4) {
bottom: -100%;
left: 0;
width: 2px;
height: 100%;
background: linear-gradient(360deg, transparent, #03e9f4);
animation: btn-anim4 1s linear infinite;
animation-delay: .75s
}
@keyframes btn-anim4 {
0% {
bottom: -100%;
}
50%,100% {
bottom: 100%;
}
}
.Jr{
left: 50px;
}
.Sr{
left: 140px;
}
我尝试更改它，以便完全渲染线条但无济于事，并且找不到如何让它们渲染，我的代码是this 的分支，我正在尝试围绕提交按钮创建动画显示在 Sr 和 Jr 按钮上。
