1、使用bootstrap实现
代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>登录</title>
<link rel="stylesheet" href="/bootstrap-3.3.7-dist/css/bootstrap.min.css">
<link rel="stylesheet" href="/css/resgister.css">
</head>
<body>
<main class="main" role="main">
<div class="container">
<div class="row">
<div class="col-md-4 col-md-offset-4">
<form class="form-container" action="/loginCheck" method="post">
<h2>用户登录</h2>
<div class="form-group">
<label>账号</label>
<input type="text" class="form-control" name="username" placeholder="请输入账号">
</div>
<div class="form-group">
<label>登录密码</label>
<input type="password" class="form-control" name="password" placeholder="请输入密码">
</div>
<button type="submit" class="btn btn-info btn-block" >登录</button>
</form>
</div>
</div>
</div>
</main>
<script src="/js/jquery-3.6.0.min.js"></script>
<script src="/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>
</body>
</html>
resgister.css为自定义文件
body{
padding: 0%;
background:url('../imags/timg.jpg') no-repeat;
background-size: cover;
}
.form-container{
padding: 10px 40px;
margin:50px 0 0 0 ;
border-radius: 5px;
background: rgba(0,0,0,0.5);
color: #ffffff;
-webkit-box-shadow: 6px 7px 31px 0px rgba(0,0,0,0.75);
-moz-box-shadow: 6px 7px 31px 0px rgba(0,0,0,0.75);
box-shadow: 6px 7px 31px 0px rgba(0,0,0,0.75);
}
.form-container h2{
text-align: center;
}
bootstrap-3.3.7-dist/css/bootstrap.min.css
jquery-3.6.0.min.js
bootstrap-3.3.7-dist/js/bootstrap.min.js
都可以通过相应官网下载
background:url(‘…/imags/timg.jpg’) no-repeat;中的time.jpg为登录背景图，可以自己替换
2、使用layui实现
代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
<title>登录</title>
<link rel="stylesheet" href="/layui/css/layui.css">
<link rel="stylesheet" href="/layui/css/admin.css">

</head>
<body>
<div class="layadmin-user-login layadmin-user-display-show" id="LAY-user-login" style="display: none;">
<div class="layadmin-user-login-main">
<div class="layadmin-user-login-box layadmin-user-login-header">
<h2>Demo-Manage</h2>
<p>基于Layui的后台管理系统</p>
</div>
<div class="layadmin-user-login-box layadmin-user-login-body layui-form">
<div class="layui-form-item">
<label class="layadmin-user-login-icon layui-icon layui-icon-username"></label>

</div>
<div class="layui-form-item">

<input type="password" id="password" lay-verify="required" placeholder="密码" readonly onfocus="this.removeAttribute('readonly');" class="layui-input">
</div>
<div class="layui-form-item" style="margin-bottom: 20px;">
<input type="checkbox" name="remember" lay-skin="primary" title="记住密码" >
<a href="#" class="layadmin-user-jump-change layadmin-link" style="margin-top: 7px;">忘记密码？</a>
</div>
<div class="layui-form-item">
<button class="layui-btn layui-btn-fluid" lay-submit id="userlogin">登 入</button>
</div>
<div class="layui-trans layui-form-item layadmin-user-login-other">
<label>社交账号登入</label>
<a href="javascript:;"><i class="layui-icon layui-icon-login-qq"></i></a>
<a href="javascript:;"><i class="layui-icon layui-icon-login-wechat"></i></a>
<a href="javascript:;"><i class="layui-icon layui-icon-login-weibo"></i></a>
<a href="#" class="layadmin-user-jump-change layadmin-link">注册帐号</a>
</div>
</div>
</div>
</div>
<script src="/layui/layui.js" type="text/javascript"></script>
<script src="/js/jquery-3.6.0.min.js"></script>
<script>
//JavaScript代码区域
layui.use(['layer','element','form','jquery'], function(){

})
}else if (result.type==='error'){
