Bootstrap笔记——登录页面

1.bootstrap中文官网

https://www.bootcss.com/

 

2.步骤

2.1复制基本模板代码

https://v3.bootcss.com/getting-started/#template

2.2复制页头代码

https://v3.bootcss.com/components/#page-header

2.3创建中间登录框部分div和底部div

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>登录界面
    </title>
     <!-- Bootstrap -->
     <link href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap.min.css" rel="stylesheet">

    </head>
<body>
<!-- 标题 -->
    <div class="page-header">
        <h1>XXXX信息系统登录界面</h1>
   </div>
<!-- 中间登录框 -->
      <div class="container-fluid">
        <div class="row">
          
          </div> 
        </div>
<!-- 页脚 -->
        <div class="footer">
                <p>&copy;版权所有：XXXXX学院XX市XX大道XXX号</p>  
                <p>邮编：530001联系邮箱：xxxxxxx@163.com</p> 
        </div>
      </div>
         
    

       <!-- jQuery (Bootstrap 的所有 JavaScript 插件都依赖 jQuery，所以必须放在前边) -->
       <script src="https://cdn.jsdelivr.net/npm/jquery@1.12.4/dist/jquery.min.js"></script>
       <!-- 加载 Bootstrap 的所有 JavaScript 插件。你也可以根据需要只加载单个插件。 -->
       <script src="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/js/bootstrap.min.js"></script>
</body>
</html>
View Code

2.4复制水平排列表单到中间登录框部分div

https://v3.bootcss.com/css/#forms-horizontal

2.5 调整样式（一个Html标签可以应用多个类样式，中间用空格隔开）

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>登录界面
    </title>
     <!-- Bootstrap -->
     <script src="js/jquery-3.4.1.js"></script>
     <link href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap.min.css" rel="stylesheet">
<style>

    .bg{
        height: 600px;
        background-image:url(/images/bg.jpg);
        background-size:cover;
    }

    .form{
        padding: 40px;
       margin-top: 175px;
       background: rgba(255,255,255,0.2);
    }

   .footer{
    height: 60px;
    padding-top:20px; 
    font-size: 14px;
    font-weight: bold;
    text-align: center;
   }
   

   
</style>
    </head>
<body>
    <div class="page-header">
        <h1>XXXX信息系统登录界面</h1>
   </div>
      <div class="container-fluid">

                        <input type="checkbox">记住我

                </div>
                <div class="form-group">
