# Bootstrap Customization: Best Practices

## **1. Introduction**

In this tutorial, we're going to learn about the best practices for customizing Bootstrap. Bootstrap is a popular front-end framework that can speed up your web development process. However, for your site to stand out, you'll need to customize the default Bootstrap styles.

By the end of this tutorial, you will learn how to efficiently customize Bootstrap in a maintainable way and avoid common pitfalls.

**Prerequisites**: Basic understanding of HTML, CSS, and Bootstrap.

## **2. Step-by-Step Guide**

### **2.1 Understanding the Bootstrap Source Code**

Before diving into customization, familiarize yourself with the Bootstrap source code. Bootstrap is built on SCSS, and its source code files are logically separated. Understanding these files will help you make targeted customizations.

### **2.2 Customizing Variables**

Bootstrap allows you to customize its default variables. This is a good starting point as it affects global styles. Locate the `_variables.scss` file and you can begin customizing.

```scss
// Customizing the primary color
$primary: #5a6268;

// Customizing the border radius
$border-radius: 0.35rem;

/* Customizing the navbar */
.navbar {
  background-color: #5a6268;
}

// Customizing the primary color
$primary: #FF6347;

// Customizing the font size
$font-size-base: 1rem;

// Don't forget to import Bootstrap to apply these changes
@import "bootstrap";

/* Overriding navbar */
.navbar {
  background-color: #FF6347;
  font-size: 1.2rem;
}

$secondary: #4682B4;
$success: #228B22;
$danger: #B22222;

@import "bootstrap";

.btn {
  font-weight: bold;
  letter-spacing: 1px;
}
