1. Containers
<!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 href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>
<div class="container">
<h1>My First Bootstrap Page</h1>
<p>This part is inside a .container class.</p>
<p>The .container class provides a responsive fixed width container.</p>
<p>Resize the browser window to see that the container width will change at different breakpoints.</p>
</div>
</body>
</html>
Containers 는 페이지를 가운데로 정렬해준다.
2. Text Colors
<!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 href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>
<div class="container mt-3">
<h2>Contextual Colors</h2>
<p>Use the contextual classes to provide "meaning through colors":</p>
<p class="text-muted">This text is muted.</p>
<p class="text-primary">This text is important.</p>
<p class="text-success">This text indicates success.</p>
<p class="text-info">This text represents some information.</p>
<p class="text-warning">This text represents a warning.</p>
<p class="text-danger">This text represents danger.</p>
<p class="text-secondary">Secondary text.</p>
<p class="text-dark">This text is dark grey.</p>
<p class="text-body">Default body color (often black).</p>
<p class="text-light">This text is light grey (on white background).</p>
<p class="text-white">This text is white (on white background).</p>
</div>
</body>
</html>
text-primary 처럼 text- 를 이용하면 글자에 색깔을 줄 수 있다.
백그라운드에 배경을 주고 싶다면 bg- 를, 테이블에 배경을 주고 싶다면
table- 을 사용하면 된다.
<div class="bg-danger"><table class="table table-hover table-dark">3. Hover Rows
<!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 href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>
<div class="container mt-3">
<h2>Hover Rows</h2>
<p>The .table-hover class enables a hover state (grey background on mouse over) on table rows:</p>
<table class="table table-hover">
<thead>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Email</th>
</tr>
</thead>
<tbody>
<tr>
<td>John</td>
<td>Doe</td>
<td>john@example.com</td>
</tr>
<tr>
<td>Mary</td>
<td>Moe</td>
<td>mary@example.com</td>
</tr>
<tr>
<td>July</td>
<td>Dooley</td>
<td>july@example.com</td>
</tr>
</tbody>
</table>
</div>
</body>
</html>
마우스를 올리면 회색으로 변한다.
