Overview of Bootstrap

Bootstrap is a free and open-source CSS framework that provides a collection of pre-built, responsive components for creating websites and web applications. It was created by Twitter, and is now maintained by a group of developers from all over the world.

Syntax

Using Bootstrap is very simple. You can include the Bootstrap CSS and JavaScript files in your HTML file, and then use the Bootstrap classes to style your HTML elements. Here is an example of how to use Bootstrap in your HTML file:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Bootstrap Example</title>
  <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
</head>
<body>
  <div class="container">
    <h1>Hello, world!</h1>
    <p>This is a Bootstrap example.</p>
  </div>
  <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>

</body>
</html>

  <div class="card-body">
    <h5 class="card-title">Card title</h5>
    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
