What is Tailwind CSS? A Beginner’s Guide

Have you ever found yourself rewriting the same CSS classes repeatedly, tweaking margins, padding, or text styles for every new project?

It can get tedious, right? Enter Tailwind CSS, a game-changer that eliminates this repetitive task by providing a utility-first approach to web design. With Tailwind, you can focus on building your unique designs without reinventing the wheel each time.

According to a 2020 survey by State of CSS, Tailwind CSS was one of the most loved CSS frameworks and it's easy to see why. But what exactly is Tailwind CSS, and how can it simplify your workflow?

Let's dive in and explore!

What is Tailwind CSS?

Tailwind CSS is a utility-first CSS framework that provides low-level utility classes to build custom designs directly in your markup. Unlike traditional CSS frameworks that offer pre-designed components, Tailwind allows you to style your elements by applying utility classes directly in your HTML.

Tailwind CSS

<button class="bg-blue-500 text-white px-4 py-2 rounded font-bold hover:bg-blue-600 transition duration-300">

Each class represents a single CSS property:

• bg-blue-500: Background color

• text-white: Text color

• px-4 py-2: Padding (x-axis and y-axis)

• rounded: Border radius

• font-bold: Font weight

• hover:bg-blue-600: Hover state

• transition duration-300: Transition effect

Vanilla CSS

Traditional CSS is written in the <style> tag:

.vanilla-button {
    background-color: #3490dc;
    color: white;
    padding: 10px 20px;
    border-radius: 5px;
    font-weight: bold;
    transition: background-color 0.3s;
}
.vanilla-button:hover {
    background-color: #2779bd;
}

The CSS class is then applied to the HTML element:

<button class="vanilla-button">

Key Features of Tailwind CSS

• Utility-First Approach: Tailwind CSS offers a plethora of utility classes that you can mix and match to create unique designs.

• Highly Customizable: You can easily customize the framework via configuration files to suit your project's needs.

• Responsive Design: With Tailwind, creating responsive designs is a breeze. It has built-in classes for different screen sizes.

• Performance: Tailwind CSS is designed to keep your final CSS file small and efficient, thanks to its purging capabilities.

Key Differences Between Tailwind & Vanilla CSS:

1. Class Naming:

   • Tailwind uses utility classes that describe the style directly (e.g., bg-blue-500).

   • Vanilla CSS uses custom class names (e.g., vanilla-button).

2. Style Application:

   • Tailwind applies styles directly in HTML using multiple classes.

   • Vanilla CSS separates styles in a CSS file or <style> tag and uses fewer, more semantic classes in HTML.

3. Customization:

   • Tailwind provides pre-defined utilities that can be composed.

   • Vanilla CSS allows for more detailed custom styles.

4. Maintainability:

   • Tailwind can lead to longer class lists in HTML but reduces the need for custom CSS.

   • Vanilla CSS keeps HTML cleaner but requires maintaining separate CSS files or blocks.

5. Learning Curve:

   • Tailwind requires learning its utility class system.

   • Vanilla CSS requires knowledge of CSS properties and values.

Both approaches have their pros and cons, and the choice often depends on project requirements and team preferences.

How Does Tailwind CSS Work?

Understanding how Tailwind CSS works can make your life so much easier. Let's break it down:

Utility Classes

Each utility class in Tailwind CSS corresponds to a single CSS property. For example, text-center aligns text to the center, and bg-blue-500 sets the background color to a specific shade of blue.

Customization

Tailwind CSS allows for extensive customization. You can modify the default configuration by editing the tailwind.config.js file. This means you can add custom colors, spacing, and even breakpoints.

Purging Unused CSS

module.exports = {
  purge: [
  content: [
    // Example content paths...
    './public/**/*.html',
    './src/**/*.{js,jsx,ts,tsx,vue}',
  ],
  theme: {
    // ...
  }
  // ...
}

One of the standout features of Tailwind CSS is its ability to purge unused CSS, which keeps your final CSS file small. This is particularly useful for performance optimization.
