What is TailwindCSS?

Tailwind CSS is a utility-first CSS framework that provides low-level utility classes to build custom designs without leaving your HTML. Unlike traditional CSS frameworks that come with predefined components, Tailwind gives you the building blocks to create your own unique designs quickly and efficiently.

Key Features of Tailwind CSS

  1. Utility-First: Instead of predefined components, Tailwind provides utility classes that you can combine to create custom designs.

  2. Highly Customizable: Tailwind can be easily customized to fit your project's specific design needs.

  3. Responsive Design: Built-in responsive modifiers make it easy to create adaptive layouts.

  4. Hover and Focus States: Easily add interactive states to your elements.

  5. Dark Mode: Built-in dark mode support for modern web applications.

Example: Traditional CSS vs Tailwind CSS

Let's compare how you might style a button using traditional CSS versus Tailwind CSS:

Traditional CSS:

<button class="btn-primary">Click me</button>
.btn-primary {
  padding: 0.5rem 1rem;
  background-color: #3490dc;
  color: white;
  border-radius: 0.25rem;
  font-weight: bold;
}

.btn-primary:hover {
  background-color: #2779bd;
}

Tailwind CSS:

<button class="px-4 py-2 bg-blue-500 text-white rounded font-bold hover:bg-blue-600">
  Click me
</button>

As you can see, with Tailwind, all the styling is done directly in the HTML using utility classes. This approach offers several benefits:

  1. Faster Development: No need to switch between HTML and CSS files or think up class names.

  2. Consistent Design: Utility classes ensure consistent spacing, colors, and other design elements across your project.

  3. Smaller CSS Bundle: Tailwind only includes the styles you actually use, resulting in smaller file sizes.

  4. Easy to Understand: The HTML clearly shows how an element is styled, making it easier for team collaboration.

When to Use Tailwind CSS

Tailwind CSS is particularly useful for:

  • Rapid prototyping and building MVPs

  • Projects where a custom design is required

  • Teams that want to maintain consistency across large projects

  • Developers who prefer having full control over their styling

While Tailwind has a learning curve, especially for those used to traditional CSS or component-based frameworks, its flexibility and efficiency make it a powerful tool in a developer's arsenal.

In the next section, we'll look at how to set up Tailwind CSS in your Next.js project, so you can start leveraging these powerful utility classes.

Setting up Tailwind CSS in a Next.js project

Setting up Tailwind CSS in your Next.js project is a straightforward process. We'll go through it step-by-step, ensuring you have everything configured correctly.

Step 1: Create a New Next.js Project

If you haven't already created a Next.js project, you can do so with the following command:

npx create-next-app@latest my-nextjs-tailwind-app
cd my-nextjs-tailwind-app

When prompted, choose the following options:

  • Would you like to use TypeScript? » No

  • Would you like to use ESLint? » Yes

  • Would you like to use Tailwind CSS? » Yes

  • Would you like to use src/ directory? » No

  • Would you like to use App Router? » Yes

  • Would you like to customize the default import alias? » No

By selecting "Yes" for Tailwind CSS, the setup process will automatically install and configure Tailwind for you.

Step 2: Verify Installation

After the installation is complete, you should see the following files in your project:

  • tailwind.config.js

  • postcss.config.js

  • app/globals.css

The globals.css file should contain the following Tailwind directives:

@tailwind base;
@tailwind components;
@tailwind utilities;

Step 3: Configure Tailwind (Optional)

The tailwind.config.js file is where you can customize Tailwind for your project. Here's what a basic configuration looks like:

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    './pages/**/*.{js,ts,jsx,tsx,mdx}',
    './components/**/*.{js,ts,jsx,tsx,mdx}',
    './app/**/*.{js,ts,jsx,tsx,mdx}',
  ],
  theme: {
    extend: {
      // Add your custom configurations here
    },
  },
  plugins: [],
}

You can extend the theme, add custom colors, or modify existing styles in this file.

Step 4: Start Using Tailwind

Now you're ready to start using Tailwind in your Next.js app. Open app/page.js and replace its content with the following:

export default function Home() {
  return (
    <main className="flex min-h-screen flex-col items-center justify-between p-24">
      <h1 className="text-4xl font-bold text-blue-600">
        Welcome to Next.js with Tailwind CSS!
      </h1>
      <p className="mt-4 text-xl text-gray-600">
        Start editing this page and see your changes in real-time.
      </p>
    </main>
  )
}

Step 5: Run Your Application

Start your development server:

npm run dev

Visit http://localhost:3000 in your browser. You should see your styled page with Tailwind CSS applied.

Troubleshooting

If you're not seeing Tailwind styles applied, check the following:

  1. Ensure globals.css is imported in your app/layout.js file.

  2. Verify that the content array in tailwind.config.js includes all your component files.

  3. Make sure you're using the correct class names as defined by Tailwind.

With Tailwind CSS now set up in your Next.js project, you're ready to start building beautiful, responsive user interfaces. In the next section, we'll dive into using basic Tailwind classes and explore the utility-first approach.

Basic Tailwind Classes and Utility-First Approach

Tailwind CSS operates on a utility-first principle, providing a wide array of low-level utility classes that you can use to build custom designs directly in your HTML. Let's explore some of the most commonly used classes and how to apply them effectively.

Understanding Utility Classes

Tailwind's utility classes are named intuitively, making them easy to remember and use. Here are some examples:

  1. Spacing:

    • p- for padding, m- for margin

    • e.g., p-4 (1rem padding), mt-2 (0.5rem top margin)

  2. Typography:

    • text- for font size, font- for font weight

    • e.g., text-lg (large text), font-bold (bold font)

  3. Colors:

    • text- for text color, bg- for background color

    • e.g., text-blue-500, bg-gray-100

  4. Layout:

    • flex, grid for display types

    • justify-, items- for alignment

    • e.g., flex justify-between items-center

  5. Sizing:

    • w- for width, h- for height

    • e.g., w-full (100% width), h-screen (100vh height)

Applying Utility Classes

Let's create a simple card component to demonstrate how these classes work together:

function Card() {
  return (
    <div className="max-w-sm mx-auto bg-white rounded-xl shadow-md overflow-hidden md:max-w-2xl">
      <div className="md:flex">
        <div className="md:flex-shrink-0">
          <img className="h-48 w-full object-cover md:w-48" src="/img/store.jpg" alt="Store front" />
        </div>
        <div className="p-8">
          <div className="uppercase tracking-wide text-sm text-indigo-500 font-semibold">Case study</div>
          <a href="#" className="block mt-1 text-lg leading-tight font-medium text-black hover:underline">
            Finding customers for your new business
          </a>
          <p className="mt-2 text-gray-500">
            Getting a new business off the ground is a lot of hard work. Here are five ideas you can use to find your first customers.
          </p>
        </div>
      </div>
    </div>
  )
}

In this example, we've used various utility classes to create a responsive card layout with proper spacing, typography, and colors.

The Utility-First Advantage

  1. Rapid Development: With utility classes, you can quickly prototype and iterate on designs without writing custom CSS.

  2. Consistency: Tailwind's predefined scale for spacing, colors, etc., helps maintain consistency across your project.

  3. Flexibility: You have the power to create unique designs without being constrained by pre-built components.

  4. Responsive Design: Tailwind's responsive modifiers (like md:) make it easy to create adaptive layouts.

Handling Hover, Focus, and Other States

Tailwind provides intuitive ways to style different states:

<button className="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded focus:outline-none focus:shadow-outline">
  Click me
</button>

Here, hover: and focus: modifiers apply styles only when the button is hovered over or focused.

Creating Custom Utilities

If you find yourself repeating certain combinations of utilities, you can extract them into custom classes using Tailwind's @apply directive in your CSS:

@layer components {
  .btn-primary {
    @apply py-2 px-4 bg-blue-500 text-white font-semibold rounded-lg shadow-md hover:bg-blue-700 focus:outline-none focus:ring-2 focus:ring-blue-400 focus:ring-opacity-75;
  }
}

Now you can use this custom class in your HTML:

<button className="btn-primary">
  Save changes
</button>

By understanding and effectively using Tailwind's utility classes, you can rapidly build custom, responsive designs without leaving your HTML. In the next section, we'll dive deeper into how Tailwind facilitates responsive design.

Responsive Design with Tailwind

Tailwind CSS makes creating responsive designs straightforward and intuitive. Instead of writing media queries in your CSS, you can use Tailwind's responsive modifiers directly in your HTML. This approach allows you to quickly adjust your layout and styling for different screen sizes.

Tailwind's Breakpoints

Tailwind comes with five default breakpoints:

  • sm: 640px

  • md: 768px

  • lg: 1024px

  • xl: 1280px

  • 2xl: 1536px

You can customize these in your tailwind.config.js file if needed.

Using Responsive Modifiers

To apply styles at a specific breakpoint, prefix any utility class with the breakpoint name followed by a colon:

<div className="w-full md:w-1/2 lg:w-1/3">
  {/* This div will be full width on mobile, half width on medium screens, and one-third width on large screens */}
</div>

Mobile-First Approach

Tailwind uses a mobile-first approach. This means that unprefixed utilities apply to all screen sizes, while prefixed utilities apply to that breakpoint and up.

<div className="text-sm md:text-base lg:text-lg">
  {/* This text will be small on mobile, base size on medium screens, and large on large screens */}
</div>

Responsive Layout Example

Let's create a responsive layout for a simple blog post:

function BlogPost() {
  return (
    <article className="mx-auto px-4 sm:px-6 lg:px-8 max-w-3xl">
      <h1 className="text-2xl sm:text-3xl md:text-4xl font-bold mb-4">
        Understanding Responsive Design with Tailwind CSS
      </h1>
      <p className="text-gray-600 mb-6">
        Published on June 30, 2024 by John Doe
      </p>
      <img 
        src="/blog-image.jpg" 
        alt="Responsive Design" 
        className="w-full h-48 sm:h-64 md:h-80 object-cover rounded-lg mb-6"
      />
      <div className="prose lg:prose-xl">
        <p>
          Responsive design is crucial in today's multi-device world. Tailwind CSS makes it easier than ever to create responsive layouts.
        </p>
        {/* More content... */}
      </div>
    </article>
  )
}

In this example:

  • The padding increases on larger screens.

  • The title font size grows as the screen size increases.

  • The image height adjusts for different screen sizes.

  • The text content uses Tailwind's prose class, which sizes up on larger screens.

Responsive Navigation

Here's an example of a responsive navigation menu:

function Navbar() {
  return (
    <nav className="bg-gray-800">
      <div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8">
        <div className="flex items-center justify-between h-16">
          <div className="flex items-center">
            <div className="flex-shrink-0">
              <img className="h-8 w-8" src="/logo.svg" alt="Logo" />
            </div>
            <div className="hidden md:block">
              <div className="ml-10 flex items-baseline space-x-4">
                <a href="#" className="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">Home</a>
                <a href="#" className="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">About</a>
                <a href="#" className="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">Services</a>
                <a href="#" className="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">Contact</a>
              </div>
            </div>
          </div>
          <div className="md:hidden">
            {/* Mobile menu button */}
            <button className="bg-gray-800 inline-flex items-center justify-center p-2 rounded-md text-gray-400 hover:text-white hover:bg-gray-700 focus:outline-none focus:ring-2 focus:ring-offset-2 focus:ring-offset-gray-800 focus:ring-white">
              <span className="sr-only">Open main menu</span>
              {/* Icon */}
            </button>
          </div>
        </div>
      </div>
      {/* Mobile menu, show/hide based on menu state */}
      <div className="md:hidden">
        <div className="px-2 pt-2 pb-3 space-y-1 sm:px-3">
          <a href="#" className="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">Home</a>
          <a href="#" className="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">About</a>
          <a href="#" className="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">Services</a>
          <a href="#" className="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">Contact</a>
        </div>
      </div>
    </nav>
  )
}

This navigation menu is fully responsive:

  • On larger screens (md and up), it displays a horizontal menu.

  • On smaller screens, it shows a mobile-friendly menu button (you'd need to add JavaScript to toggle the mobile menu's visibility).

By leveraging Tailwind's responsive modifiers, you can create complex, responsive layouts with ease, all within your HTML. In the next section, we'll dive deeper into creating a fully responsive navbar component.

Creating a Responsive Navbar

A well-designed, responsive navbar is crucial for providing a good user experience across all devices. In this section, we'll build a fully responsive navbar using Tailwind CSS and a bit of React for interactivity.

Basic Structure

First, let's create the basic structure of our navbar:

import React, { useState } from 'react';
import Link from 'next/link';

const Navbar = () => {
  const [isOpen, setIsOpen] = useState(false);

  return (
    <nav className="bg-gray-800">
      <div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8">
        <div className="flex items-center justify-between h-16">
          {/* Logo */}
          <div className="flex-shrink-0">
            <Link href="/" className="text-white font-bold text-xl">
              Logo
            </Link>
          </div>

          {/* Desktop Menu */}
          <div className="hidden md:block">
            {/* ... we'll add menu items here */}
          </div>

          {/* Mobile menu button */}
          <div className="md:hidden">
            {/* ... we'll add the button here */}
          </div>
        </div>
      </div>

      {/* Mobile Menu */}
      <div className={`md:hidden ${isOpen ? 'block' : 'hidden'}`}>
        {/* ... we'll add mobile menu items here */}
      </div>
    </nav>
  );
};

export default Navbar;

Adding Menu Items

Now, let's add the menu items for both desktop and mobile views:

// ... previous code

{/* Desktop Menu */}
<div className="hidden md:block">
  <div className="ml-10 flex items-baseline space-x-4">
    <Link href="/" className="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">
      Home
    </Link>
    <Link href="/about" className="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">
      About
    </Link>
    <Link href="/services" className="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">
      Services
    </Link>
    <Link href="/contact" className="text-gray-300 hover:bg-gray-700 hover:text-white px-3 py-2 rounded-md text-sm font-medium">
      Contact
    </Link>
  </div>
</div>

{/* Mobile menu button */}
<div className="md:hidden">
  <button 
    onClick={() => setIsOpen(!isOpen)} 
    className="inline-flex items-center justify-center p-2 rounded-md text-gray-400 hover:text-white hover:bg-gray-700 focus:outline-none focus:ring-2 focus:ring-offset-2 focus:ring-offset-gray-800 focus:ring-white"
  >
    <span className="sr-only">Open main menu</span>
    {!isOpen ? (
      <svg className="block h-6 w-6" xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" aria-hidden="true">
        <path strokeLinecap="round" strokeLinejoin="round" strokeWidth="2" d="M4 6h16M4 12h16M4 18h16" />
      </svg>
    ) : (
      <svg className="block h-6 w-6" xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" aria-hidden="true">
        <path strokeLinecap="round" strokeLinejoin="round" strokeWidth="2" d="M6 18L18 6M6 6l12 12" />
      </svg>
    )}
  </button>
</div>

{/* Mobile Menu */}
<div className={`md:hidden ${isOpen ? 'block' : 'hidden'}`}>
  <div className="px-2 pt-2 pb-3 space-y-1 sm:px-3">
    <Link href="/" className="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">
      Home
    </Link>
    <Link href="/about" className="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">
      About
    </Link>
    <Link href="/services" className="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">
      Services
    </Link>
    <Link href="/contact" className="text-gray-300 hover:bg-gray-700 hover:text-white block px-3 py-2 rounded-md text-base font-medium">
      Contact
    </Link>
  </div>
</div>

Explaining the Responsive Design

  1. Desktop Menu:

    • Uses hidden md:block to hide on small screens and show on medium screens and up.

    • Horizontal layout achieved with flex and space-x-4.

  2. Mobile Menu Button:

    • Visible only on small screens with md:hidden.

    • Toggles the isOpen state to show/hide the mobile menu.

  3. Mobile Menu:

    • Conditionally rendered based on the isOpen state.

    • Stacked layout for easy touch interaction on small screens.

  4. Responsive Padding:

    • Uses px-4 sm:px-6 lg:px-8 to increase horizontal padding as screen size grows.
  5. Interactive Elements:

    • All links and buttons have hover and focus states for better user experience.

Enhancing Accessibility

To improve accessibility, we've included:

  • sr-only class for screen reader text on the mobile menu button.

  • Semantic HTML structure with nav element.

  • Proper aria labels and roles (you might want to add more depending on your specific needs).

Further Improvements

You could enhance this navbar further by:

  • Adding a dropdown for nested menu items.

  • Implementing an active state for the current page.

  • Adding smooth transitions for the mobile menu open/close action.

  • Including a search bar or user account options.

This responsive navbar provides a solid foundation that works well on both mobile and desktop views. It uses Tailwind's utility classes to create a sleek design without any custom CSS, and React's state management for the mobile menu toggle functionality.

In the next section, we'll create a responsive footer to complement our navbar.

A well-designed footer can provide valuable information and navigation options to your users. Let's create a responsive footer that looks great on all screen sizes using Tailwind CSS.

Basic Structure

First, let's create the basic structure of our footer:

import React from 'react';
import Link from 'next/link';

const Footer = () => {
  return (
    <footer className="bg-gray-800 text-white">
      <div className="max-w-7xl mx-auto py-12 px-4 sm:px-6 lg:py-16 lg:px-8">
        <div className="xl:grid xl:grid-cols-3 xl:gap-8">
          {/* Company Info */}
          <div className="space-y-8 xl:col-span-1">
            {/* Logo */}
            <img className="h-10" src="/logo.svg" alt="Company name" />
            <p className="text-gray-400 text-base">
              Making the world a better place through constructing elegant hierarchies.
            </p>
            {/* Social Links */}
            <div className="flex space-x-6">
              {/* Add social media icons/links here */}
            </div>
          </div>

          {/* Footer Links */}
          <div className="mt-12 grid grid-cols-2 gap-8 xl:mt-0 xl:col-span-2">
            <div className="md:grid md:grid-cols-2 md:gap-8">
              {/* Solutions */}
              <div>
                <h3 className="text-sm font-semibold text-gray-400 tracking-wider uppercase">
                  Solutions
                </h3>
                <ul className="mt-4 space-y-4">
                  {/* Add solution links here */}
                </ul>
              </div>
              {/* Support */}
              <div className="mt-12 md:mt-0">
                <h3 className="text-sm font-semibold text-gray-400 tracking-wider uppercase">
                  Support
                </h3>
                <ul className="mt-4 space-y-4">
                  {/* Add support links here */}
                </ul>

Explaining the Responsive Design

  1. Overall Layout:

    • Uses a max-width container (max-w-7xl) for large screens.

    • Responsive padding with px-4 sm:px-6 lg:px-8.

  2. Grid System:

    • On extra-large screens (xl:), uses a 3-column grid for main sections.

    • On medium screens and up (md:), uses a 2-column grid for link sections.

    • On small screens, stacks all content vertically.

  3. Spacing:

    • Consistent spacing with space-y-4 for list items.

    • Responsive vertical spacing with py-12 lg:py-16.

  4. Typography:

    • Uppercase, semibold headings for link sections.

    • Responsive text alignment for copyright (centered on xl: screens).

  5. Hover Effects:

    • Links and social icons have hover states for better interactivity.

Accessibility Considerations

  • Use of semantic HTML with the footer element.

  • Proper heading hierarchy with h3 for section titles.

  • "sr-only" class for screen reader text on social media icons.

Further Improvements

You could enhance this footer by:

  • Adding a newsletter signup form.

  • Implementing a collapsible accordion for mobile view to save space.

  • Including location information or a mini contact form.

  • Adding animations or transitions for a more polished look.

This responsive footer provides a comprehensive structure that adapts well to different screen sizes. It uses Tailwind's utility classes to create a cohesive design that matches the navbar we created earlier, ensuring a consistent look and feel across your website.

In the next and final section, we'll cover some best practices and tips for using Tailwind CSS effectively in your Next.js projects.

Best Practices and Tips for Tailwind CSS in Next.js

As you become more comfortable with Tailwind CSS in your Next.js projects, consider these best practices and tips to enhance your development experience and maintain clean, efficient code.

1. Customize Your Tailwind Configuration

Tailor Tailwind to your project's needs by customizing tailwind.config.js:

module.exports = {
  theme: {
    extend: {
      colors: {
        'brand-blue': '#1992d4',
      },
      fontFamily: {
        sans: ['Inter', 'sans-serif'],
      },
    },
  },
  // ...
}

This allows you to use custom colors (text-brand-blue) and fonts (font-sans) throughout your project.

2. Use the @apply Directive for Repeated Utility Patterns

For frequently used combinations of utilities, consider extracting them into custom classes:

@layer components {
  .btn-primary {
    @apply py-2 px-4 bg-blue-500 text-white font-semibold rounded-lg shadow-md hover:bg-blue-700 focus:outline-none focus:ring-2 focus:ring-blue-400 focus:ring-opacity-75;
  }
}

Now you can use className="btn-primary" in your JSX.

3. Leverage Tailwind's JIT (Just-In-Time) Mode

Next.js 13+ and Tailwind CSS 3.0+ use JIT mode by default, which offers:

  • Faster build times

  • Smaller CSS files

  • The ability to use arbitrary values

<div className="top-[117px]">
  {/* This works in JIT mode */}
</div>

4. Organize Complex Components with BEM-like Naming

For complex components, consider using BEM-like naming combined with Tailwind:

<div className="card">
  <div className="card__header">
    <h2 className="card__title">Title</h2>
  </div>
  <div className="card__body">
    <p className="card__text">Content</p>
  </div>
</div>
@layer components {
  .card {
    @apply bg-white rounded-lg shadow-md overflow-hidden;
  }
  .card__header {
    @apply px-6 py-4 bg-gray-100;
  }
  .card__title {
    @apply text-xl font-semibold text-gray-800;
  }
  .card__body {
    @apply px-6 py-4;
  }
  .card__text {
    @apply text-gray-700;
  }
}

5. Use Tailwind's Built-in Dark Mode

Enable dark mode in your tailwind.config.js:

module.exports = {
  darkMode: 'class',
  // ...
}

Then use it in your components:

<div className="bg-white dark:bg-gray-800 text-black dark:text-white">
  {/* Content */}
</div>

6. Optimize for Production

Tailwind automatically purges unused styles in production. Ensure your content sources are correctly configured in tailwind.config.js:

module.exports = {
  content: [
    "./pages/**/*.{js,ts,jsx,tsx}",
    "./components/**/*.{js,ts,jsx,tsx}",
  ],
  // ...
}

7. Use Tailwind CSS Intellisense

Install the Tailwind CSS IntelliSense extension for your code editor. It provides autocomplete, syntax highlighting, and linting for Tailwind CSS classes.

8. Maintain Consistency with a Design System

Create a design system using Tailwind's configuration:

module.exports = {
  theme: {
    extend: {
      spacing: {
        '72': '18rem',
        '84': '21rem',
        '96': '24rem',
      },
      fontSize: {
        'xxs': '.625rem',
      },
    },
  },
  // ...
}

This ensures consistency across your project and makes it easier to maintain and scale your designs.

9. Use @screen Directive for Media Queries

When you need to write custom CSS, use the @screen directive to reference Tailwind's breakpoints:

@layer components {
  .custom-component {
    @apply text-sm;

    @screen md {
      @apply text-base;
    }
  }
}

10. Separate Concerns with Tailwind

While Tailwind encourages utility-first CSS, it's still beneficial to separate layout utilities from styling utilities in your JSX for better readability:

<div className="flex items-center justify-between p-4 md:p-6">
  <div className="text-lg font-bold text-gray-800 hover:text-blue-600">
    {/* Content */}
  </div>
</div>

By following these best practices and tips, you'll be able to create more maintainable, efficient, and consistent designs in your Next.js projects using Tailwind CSS. Remember, the key is to find the right balance between utility classes and custom components that work best for your team and project.
