Question

我在叠加方面遇到了一些麻烦。我想创建一个页面，按一下按钮就可以了，＆＃34;登录＆＃34;按钮，一个小弹出窗口应该显示为接受用户名和密码等。背景应该应用覆盖。

Answer 1

您可以使用bootstrap模式执行此操作并在其中创建登录表单。如下所示。

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
  <h2>Modal Example</h2>
  <!-- Trigger the modal with a button -->
  <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>

  <!-- Modal -->
  <div class="modal fade" id="myModal" role="dialog">
    <div class="modal-dialog">

      <!-- Modal content-->
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
          <h4 class="modal-title">Modal Header</h4>
        </div>
        <div class="modal-body">
          <p>Some text in the modal.</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        </div>
      </div>

    </div>
  </div>

</div>

</body>
</html>

首先，您使用透明背景创建一个覆盖整个页面的分部。之后在该div中创建另一个新分区。

#model{
	position:fixed;
	top:0px;
	left:0px;
	width:100%;
	height:800px ; //Height of the screen 
	background:rgba(30,30,30,0.7);
}

<div id="model">
	// your form here goes ...
</div>
