Tailwind CSS Tutorial: Frequently Used Classes and Examples

Tailwind CSS is a utility-first CSS framework that allows you to quickly build custom designs without having to write custom CSS. Tailwind provides a set of utility classes that can be directly applied to HTML elements, enabling you to style your application easily and consistently.

In this tutorial, we will explore frequently used Tailwind CSS classes and provide examples to show how they can be used to build responsive, flexible, and modern web designs.

1. Setting Up Tailwind CSS

Step 1: Install Tailwind CSS

If you haven't already set up a Tailwind CSS project, you can do so by following these steps:

  1. Initialize a new project (if you haven't done so):
bash
npm init -y
  1. Install Tailwind CSS via npm:
bash
npm install -D tailwindcss postcss autoprefixer
  1. Initialize Tailwind CSS:
bash
npx tailwindcss init

This command will generate a tailwind.config.js file in your project.

  1. Configure Tailwind by adding the following to your CSS file (e.g., src/styles.css):
css
@tailwind base;
@tailwind components;
@tailwind utilities;
  1. In your tailwind.config.js file, configure the content paths for Tailwind to purge unused styles in production:
javascript
module.exports = {
  content: [
    "./src/**/*.{html,js,ts,jsx,tsx}",
  ],
  theme: {
    extend: {},
  },
  plugins: [],
}
  1. Build your CSS with the following command:
bash
npx tailwindcss -o build.css --watch

This will build your Tailwind CSS and generate the build.css file.

2. Frequently Used Tailwind CSS Classes

Tailwind provides utility classes for almost every style you could think of. Here are some frequently used classes with examples:

2.1 Flexbox Layout

Tailwind makes it easy to create flexible layouts using Flexbox.

  • .flex: Applies flexbox to an element.
  • .flex-row: Aligns flex items in a row (default).
  • .flex-col: Aligns flex items in a column.
  • .justify-center: Centers items horizontally.
  • .items-center: Centers items vertically.
html
<div class="flex justify-center items-center h-screen">
  <div class="p-6 bg-blue-500 text-white">Centered Content</div>
</div>

In this example, h-screen makes the container full-height, and flex, justify-center, and items-center center the content both vertically and horizontally.

2.2 Grid Layout

Tailwind makes working with grids simple.

  • .grid: Applies grid layout.
  • .grid-cols-2: Creates a grid with two columns.
  • .gap-4: Adds a gap between grid items.
html
<div class="grid grid-cols-2 gap-4">
  <div class="p-4 bg-green-500 text-white">Item 1</div>
  <div class="p-4 bg-blue-500 text-white">Item 2</div>
  <div class="p-4 bg-red-500 text-white">Item 3</div>
  <div class="p-4 bg-yellow-500 text-white">Item 4</div>
</div>

This example creates a two-column grid with items having gaps between them.

2.3 Spacing

Tailwind provides a set of spacing utilities that allow you to control margin, padding, and gap.

  • .m-4: Sets margin on all sides.
  • .p-4: Sets padding on all sides.
  • .mt-4: Sets margin-top.
  • .mb-4: Sets margin-bottom.
  • .space-x-4: Sets horizontal spacing between elements.
html
<div class="p-4 m-4 bg-gray-200">
  <p class="mb-4">This is a paragraph with margin-bottom.</p>
  <div class="space-x-4">
    <button class="px-4 py-2 bg-blue-500 text-white">Button 1</button>
    <button class="px-4 py-2 bg-green-500 text-white">Button 2</button>
  </div>
</div>

In this example, p-4 adds padding around the container, m-4 adds margin, and space-x-4 adds horizontal spacing between buttons.

2.4 Typography

Tailwind provides utilities to adjust fonts, sizes, weights, and alignment.

  • .text-xl: Sets the text size to extra-large.
  • .font-bold: Sets the font weight to bold.
  • .text-center: Centers the text horizontally.
  • .leading-tight: Sets tight line height.
html
<div class="text-center">
  <h1 class="text-3xl font-bold">Tailwind CSS Tutorial</h1>
  <p class="text-lg leading-tight">Learn how to use Tailwind CSS to build modern websites.</p>
</div>

2.5 Background and Colors

Tailwind allows you to quickly apply background colors, text colors, and more.

  • .bg-blue-500: Applies a blue background.
  • .text-white: Changes text color to white.
  • .bg-gradient-to-r: Creates a gradient background.
html
<div class="bg-blue-500 text-white p-6">
  <h2 class="text-xl font-bold">A Blue Box with White Text</h2>
  <p>This box has a blue background and white text.</p>
</div>

<!-- Gradient Background -->
<div class="bg-gradient-to-r from-green-400 to-blue-500 text-white p-6">
  <p>This is a gradient background.</p>
</div>

In this example, the first div has a solid blue background, while the second div uses a gradient from green to blue.

2.6 Borders and Shadows

  • .border: Adds a border to the element.
  • .border-2: Sets the border thickness to 2px.
  • .rounded: Adds rounded corners.
  • .shadow-lg: Adds a large shadow effect.
html
<div class="border-2 border-gray-500 rounded-lg p-6 shadow-lg">
  <h3 class="text-xl">Card with Border and Shadow</h3>
  <p>This card has a 2px border, rounded corners, and a large shadow effect.</p>
</div>

2.7 Responsiveness

Tailwind makes it easy to build responsive layouts using breakpoint classes.

  • .sm:: Small screen (min-width: 640px).
  • .md:: Medium screen (min-width: 768px).
  • .lg:: Large screen (min-width: 1024px).
  • .xl:: Extra large screen (min-width: 1280px).
html
<div class="bg-blue-500 sm:text-sm md:text-lg lg:text-xl xl:text-2xl">
  <p>This text will change size based on the screen width.</p>
</div>

In this example, the text size will adjust based on the screen size.

3. Building a Simple Layout with Tailwind CSS

Let’s create a simple responsive card layout using Tailwind CSS:

html
<div class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6 p-6">
  <div class="bg-white border border-gray-200 rounded-lg shadow-lg p-6">
    <h2 class="text-xl font-bold mb-4">Card 1</h2>
    <p>This is the content of card 1.</p>
  </div>
  <div class="bg-white border border-gray-200 rounded-lg shadow-lg p-6">
    <h2 class="text-xl font-bold mb-4">Card 2</h2>
    <p>This is the content of card 2.</p>
  </div>
  <div class="bg-white border border-gray-200 rounded-lg shadow-lg p-6">
    <h2 class="text-xl font-bold mb-4">Card 3</h2>
    <p>This is the content of card 3.</p>
  </div>
</div>

In this example, we create a responsive grid layout with cards. On smaller screens, the cards are displayed in a single column, but on medium and large screens, they display in two and three columns respectively.

4. Conclusion

Tailwind CSS offers a utility-first approach to styling that allows you to build custom designs quickly and efficiently without writing custom CSS.

Building strong foundational knowledge in frontend development topics

 These topics are essential for building strong foundational knowledge, and each comes with a simple solution or code snippet to illustrate the concept. 1. What is the difference between HTML, CSS, and JavaScript? Answer : HTML (Hypertext Markup Language) is used for structuring web content (headings, paragraphs, images, links, etc.). CSS (Cascading Style Sheets) is used for styling the layout, design, and appearance of the web content. JavaScript is used for adding interactivity and dynamic behavior to the website (e.g., form validation, animations, events). html <!-- HTML --> < div class = "box" > </ div > css /* CSS */ .box { width : 100px ; height : 100px ; background-color : blue; } javascript // JavaScript document . querySelector ( '.box' ). addEventListener ( 'click' , function ( ) { alert ( 'Box clicked!' ); }); 2.
