Taiwind Questions

Tailwind CSS is a utility-first CSS framework that provides low-level utility classes for building custom designs.
Unlike Bootstrap, which provides pre-designed components, Tailwind gives you the tools to build unique designs from scratch.

npm install -D tailwindcss
npx tailwindcss init

<script src="https://cdn.tailwindcss.com"></script>
<div class="bg-blue-500 text-white p-4">Hello Tailwind</div>

Edit tailwind.config.js:
module.exports = {
  theme: {
    extend: {
      colors: {
        primary: '#1DA1F2',
      },
    },
  },
}

Variants are used to apply styles conditionally:
<button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
  Hover me
</button>

<div class="flex justify-center items-center h-screen">
  <div class="bg-gray-300 p-5">Centered</div>
</div>

<div class="grid grid-cols-1 md:grid-cols-3 gap-4">
  <div class="bg-red-100 p-4">Box 1</div>
  <div class="bg-red-200 p-4">Box 2</div>
  <div class="bg-red-300 p-4">Box 3</div>
</div>

Add to tailwind.config.js:
theme: {
  extend: {
    fontFamily: {
      custom: ['"Open Sans"', 'sans-serif'],
    },
  },
}
Use in HTML:
<p class="font-custom">Custom font text</p>

Use @apply in CSS to include Tailwind classes:
.btn {
  @apply bg-blue-500 text-white px-4 py-2 rounded;
}

In tailwind.config.js:
module.exports = {
  content: ['./src/**/*.{html,js}'],
  theme: {
    extend: {},
  },
  plugins: [],
}

`w-` sets the exact width of an element.
`max-w-` sets the maximum width the element can grow to.
Example:
<div class="w-64">Fixed width</div>
<div class="max-w-xl">Max width</div>

<button class="px-4 py-2 text-sm md:text-base bg-green-500 rounded">
  Responsive Button
</button>

Use responsive utilities:
<div class="block md:hidden">Visible only on mobile</div>
<div class="hidden md:block">Hidden on mobile</div>

Use `p-` for padding and `m-` for margin:
<div class="p-4 m-2">Box with spacing</div>

<button class="bg-gray-300 hover:bg-gray-500 text-white px-4 py-2">
  Hover me
</button>

Pseudo-classes like `hover:`, `focus:`, `active:` add state-based styles.
Example:
<input class="focus:outline-none focus:ring-2 focus:ring-blue-500">

Add to tailwind.config.js:
theme: {
  screens: {
    'xs': '480px',
    'sm': '640px',
    ...
  }
}

<img src="..." class="w-full h-auto">

Use `z-` classes:
z-0, z-10, z-20, z-30, z-40, z-50
Example:
<div class="relative z-50">Top layer</div>

<header class="fixed top-0 left-0 w-full bg-white shadow z-50">
  My Fixed Header
</header>

<div class="grid grid-cols-3 gap-4">
  <div class="bg-red-200">1</div>
  <div class="bg-red-300">2</div>
  <div class="bg-red-400">3</div>
</div>

Use `animate-` utilities with plugins:
<div class="animate-bounce">Bouncing Element</div>

Use `shadow` classes:
shadow-sm, shadow, shadow-md, shadow-lg
Example:
<div class="shadow-lg p-4 bg-white">Box with shadow</div>

<div class="fixed inset-0 flex justify-center items-center bg-black bg-opacity-50">
  <div class="bg-white p-6 rounded">Modal content</div>
</div>

Use `flex` with `items-center`:
<div class="flex items-center h-64">
  <p>Centered text</p>
</div>

`object-cover` ensures the image covers its container without distortion.
Example:
<img class="w-full h-64 object-cover" src="image.jpg">

Use `rounded-full` with fixed width/height:
<img class="w-24 h-24 rounded-full" src="profile.jpg">

`container` centers the content and applies responsive max-widths.
Example:
<div class="container mx-auto px-4">Centered content</div>

<nav class="flex items-center justify-between flex-wrap bg-blue-500 p-4">
  <div class="text-white font-bold text-xl">Logo</div>
  <div class="block md:hidden">☰</div>
  <div class="w-full block flex-grow md:flex md:items-center md:w-auto">
    <a class="block mt-4 md:inline-block md:mt-0 text-white mr-4" href="#">Home</a>
  </div>
</nav>

Use the `truncate` class:
<p class="truncate w-48">This is a long text that will be truncated</p>

Use `hover:` prefix to style on hover:
<button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
  Hover Me
</button>

Use prefixes like `sm:`, `md:`, `lg:` for breakpoints:
<div class="p-2 md:p-6 lg:p-10">Responsive Padding</div>

Use `shadow`, `shadow-md`, `shadow-lg`, etc.:
<div class="shadow-lg p-4">Box with Shadow</div>

Use `z-{index}`:
<div class="relative z-50">Z-index 50</div>

Use `hidden sm:block`:
<div class="hidden sm:block">Visible only on screens ≥ 640px</div>

Use `text-left`, `text-center`, `text-right`:
<p class="text-center">This is centered text</p>

Use `pointer-events-none`:
<div class="pointer-events-none">No click actions allowed here</div>

Limits the max width of the element to the `xl` screen size:
<div class="max-w-screen-xl mx-auto">Centered and max-width limited</div>

Define it in `tailwind.config.js`:
module.exports = {
  theme: {
    extend: {
      fontFamily: {
        custom: ['YourFontName', 'sans-serif'],
      },
    },
  },
}

Then use it:
<p class="font-custom">This uses a custom font</p>

Enable in `tailwind.config.js`:
module.exports = {
  darkMode: 'class',
}

Then use:
<div class="bg-white dark:bg-gray-800 text-black dark:text-white">
  Content switches with dark mode
</div>

Use `transition` classes:
<button class="bg-blue-500 hover:bg-blue-700 text-white px-4 py-2 transition duration-300 ease-in-out">
  Hover me
</button>

Utility-first classes are single-purpose CSS classes:
Example:
<div class="text-center bg-red-500 p-4 text-white">Utility-based styling</div>

<div class="bg-white shadow-md rounded-lg p-6 max-w-sm">
  <h2 class="text-xl font-bold mb-2">Card Title</h2>
  <p class="text-gray-600">Card content goes here.</p>
</div>

<div class="grid grid-cols-3 gap-4">
  <div class="bg-red-200 p-4">1</div>
  <div class="bg-green-200 p-4">2</div>
  <div class="bg-blue-200 p-4">3</div>
</div>

<img src="image.jpg" class="w-full h-auto" alt="Responsive Image">

Use `flex`, `flex-col`, `flex-row`, etc.:
<div class="flex flex-row space-x-4">
  <div>Item 1</div>
  <div>Item 2</div>
</div>

<img src="avatar.jpg" class="w-16 h-16 rounded-full" alt="Avatar">

Add animation utilities:
<div class="animate-bounce">Bouncing Element</div>

Use `truncate` with `overflow-hidden` and `whitespace-nowrap`:
<p class="truncate w-48">This is a long piece of text that will be cut off</p>

Use `flex items-center justify-center`:
<div class="flex items-center justify-center h-screen">
  <p>Centered content</p>
</div>

<header class="sticky top-0 bg-white shadow z-50">
  <nav class="p-4">Sticky Header</nav>
</header>

Add to tailwind.config.js:
module.exports = {
  theme: {
    extend: {
      colors: {
        customBlue: '#1fb6ff',
      }
    }
  }
}

<nav class="flex flex-wrap justify-between items-center p-4">
  <div>Logo</div>
  <div class="hidden md:flex space-x-4">
    <a href="#">Home</a>
    <a href="#">About</a>
  </div>
</nav>

It allows applying utility classes inside a CSS file:
.btn {
  @apply px-4 py-2 bg-blue-500 text-white rounded;
}

Use the `hover:` prefix:
<button class="bg-green-500 hover:bg-green-700 text-white py-2 px-4">Hover me</button>

<div class="hidden md:block">
  Visible only on medium screens and above
</div>

<div class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4">
  <div class="bg-gray-200 p-4">Column 1</div>
  <div class="bg-gray-300 p-4">Column 2</div>
  <div class="bg-gray-400 p-4">Column 3</div>
</div>

JIT (Just-in-Time) compiles styles as you write them:
Enable in tailwind.config.js:
module.exports = {
  mode: 'jit',
  ...
}

Use `shadow`, `shadow-md`, `shadow-lg`, etc.:
<div class="shadow-lg p-6 bg-white">Box with shadow</div>

Use `z-{index}`:
<div class="relative z-10">On top</div>
<div class="relative z-0">Behind</div>

Use `leading-{size}`:
<p class="leading-relaxed">This text has relaxed line height.</p>

Centers and sets max-width for content:
<div class="container mx-auto">Centered content</div>

<div class="hover:scale-105 transition-transform duration-300">
  Hover to scale
</div>

<div class="border border-red-500 p-4">Bordered box</div>

<div class="w-full h-screen bg-gray-100">
  Full page container
</div>

<div class="w-full h-full">
  Full width and height content
</div>

It applies typographic styles to content like articles:
<article class="prose">
  <h1>Title</h1>
  <p>Body text</p>
</article>

<div class="transition duration-500 ease-in-out hover:bg-blue-500">
  Hover me
