download first.

Boostrap has this link and they're hosting the bootstrap CSS files for us.
so we don't even need to include it in our project.
All we need to do is add this line into our HTML.

jumbotron

https://getbootstrap.com/docs/4.0/components/jumbotron/

<div class="jumbotron">
	  <h1 class="display-4">Hello, world!</h1>
	  <p class="lead">This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.</p>
	  <hr class="my-4">
	  <p>It uses utility classes for typography and spacing to space content out within the larger container.</p>
	  <p class="lead">
	    <a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a>
	  </p>
	</div>

Use Bootstrap’s JavaScript modal plugin to add dialogs to your site for lightboxes, user notifications, or completely custom content.

<!-- Button trigger modal -->
	<button type="button" class="btn btn-danger" data-toggle="modal" data-target="#exampleModal">
	  Launch demo modal
	</button>

	<!-- Modal -->
	<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
	  <div class="modal-dialog" role="document">
	    <div class="modal-content">
	      <div class="modal-header">
	        <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
	        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
	          <span aria-hidden="true">&times;</span>
	        </button>
	      </div>
	      <div class="modal-body">
	        ...
	      </div>
	      <div class="modal-footer">
	        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
	        <button type="button" class="btn btn-primary">Save changes</button>
	      </div>
	    </div>
	  </div>
	</div>

If you click launch demo modal button, pop-up window is created.

If you don't have the script below,
launch demo model doesn't make a pop-up window.

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

button

if you want to use red button,
use class="btn btn-danger"

<button type="button" class="btn btn-danger" data-toggle="modal" data-target="#exampleModal">
<!--index.html-->

if you want 'btn btn-danger' to be orange, not red
, create a stylesheet at the top.

<head>
	<title>Bootstrap</title>
	<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous">
	<link rel="stylesheet" type="text/css" href="style.css">
</head>
<!--index.html-->

.btn-danger{
	background-color: orange;
}
/*style.css*/

.btn-danger{
	background-color: orange;
}

.btn-danger:hover{
	background-color: black;
}

/*style.css에 hover모드 추가*/

button에 마우스대면 black으로 변함!
