Vite with CSS Tutorial

1. Introduction

This tutorial aims to guide you through using CSS with Vite, a powerful tool that significantly enhances your development workflow. By the end of this tutorial, you will understand how to effectively utilize CSS in a Vite project.

What will you learn:

• How to set up Vite for a new project
• How to include CSS in Vite
• How to use CSS pre-processors with Vite
• Best practices when working with CSS and Vite

Prerequisites:

• Basic knowledge of HTML, CSS, and JavaScript
• Node.js and npm installed on your system

2. Step-by-Step Guide

Setting up Vite

Before we start working with CSS, we first need to set up a new Vite project. Install Vite globally with the following command:

npm install -g create-vite

Create a new Vite project:

create-vite my-vite-project

Navigate into your new project directory and install the dependencies:

cd my-vite-project
npm install

Including CSS in Vite

One of the simplest ways to include CSS in Vite is to import it directly in your JavaScript file. Here is an example:

// main.js
import './style.css'

In your style.css file, you can write your CSS rules:

/* style.css */
body {
  background-color: lightblue;
}

Using CSS Pre-processors

Vite also supports CSS pre-processors like Less, Sass, and Stylus. To use them, you must first install the corresponding package. For example, to use Sass, install the sass package:

npm install -D sass

Then, you can import your .scss files directly in your JavaScript:

// main.js
import './style.scss'

3. Code Examples

Here are a few examples of how you can use CSS with Vite.

Example 1: Importing CSS in JavaScript

// main.js
import './style.css'

/* style.css */
body {
  background-color: lightblue;
}

Example 2: Using Sass with Vite

First, install the sass package:

npm install -D sass

Then, import your .scss file in JavaScript:

// main.js
import './style.scss'

/* style.scss */
$bg-color: lightblue;

body {
  background-color: $bg-color;
}
