1. Introduction

This tutorial aims to guide you through the process of customizing Bootstrap's default typography and color themes. By the end of this tutorial, you will be able to:

• Understand how to override Bootstrap's default typography and color styles
• Customize your website's design to align with its brand identity

Prerequisites: Basic knowledge of HTML, CSS, and familiarity with Bootstrap.

2. Step-by-Step Guide

Bootstrap is a popular CSS framework that includes predefined classes for layout, typography, colors, and more. While these defaults are useful, there will be times when you want to customize these styles to match your specific design requirements.

Customizing Typography

To customize typography, you'll be overriding Bootstrap's default styles in your own CSS file.

body {
  font-family: Arial, sans-serif;
  color: #333;
}

The above code changes the default font to Arial and the text color to dark gray.

Customizing Colors

Bootstrap has a set of color classes like .text-primary, .bg-success, etc. To change these, you'll need to override these in your own CSS file.

.text-primary {
  color: #ff0000 !important;
}

The above code changes the .text-primary color to red.

Remember to include your CSS file after the Bootstrap CSS file to ensure your styles take precedence.

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<link rel="stylesheet" href="styles.css">

In the above code, styles.css is the custom CSS file.

3. Code Examples

Example 1: Changing Typography

/* styles.css */
body {
  font-family: 'Times New Roman', Times, serif;
  color: #000080;
}

In this example, we change the default font to 'Times New Roman' and the text color to navy blue.

Example 2: Changing Color Themes

/* styles.css */
.text-success {
  color: #ff4500 !important;
}

.bg-primary {
  background-color: #ffa500 !important;
}

In this example, we change the text color for the .text-success class to orange-red, and the background color for the .bg-primary class to orange.
