Getting Started with Bootstrap
In this tutorial, we'll introduce Bootstrap, a popular CSS framework, and demonstrate how to use it in a simple project. We'll cover its key features, including the grid system, components, and utility classes.
What is Bootstrap?
Bootstrap is a powerful, open-source CSS framework designed to help developers create responsive, mobile-first websites. It includes a grid system, pre-built components, and utility classes that simplify the web design process.
Using Bootstrap in your project
To start using Bootstrap, you can either download the files from the official website (https://getbootstrap.com/) or use the CDN links. For this tutorial, we'll use the CDN links.
Add the following links to the head section of your HTML file:
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<link href="https://firstname.lastname@example.org/dist/css/bootstrap.min.css" rel="stylesheet" />
<title>My Bootstrap Website</title>

Bootstrap grid system
The Bootstrap grid system uses a series of containers, rows, and columns to create responsive layouts. Containers hold rows, and rows hold columns. The grid is based on a 12-column layout.
<div class="col-sm-4">Column 1</div>
<div class="col-sm-4">Column 2</div>
<div class="col-sm-4">Column 3</div>
Bootstrap includes pre-built components like buttons, forms, and navigation. To use a component, simply add the appropriate Bootstrap classes to your HTML elements.
<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-secondary">Secondary</button>
<button type="button" class="btn btn-success">Success</button>
Bootstrap utility classes
Utility classes in Bootstrap provide quick ways to apply common CSS properties. They help you customize elements without writing additional CSS code.
<div class="mt-5">Margin top 5</div>
<div class="mb-3">Margin bottom 3</div>
<div class="pt-2">Padding top 2</div>
<div class="pb-4">Padding bottom 4</div>
