Tailwind CSS Ściągawka: Kompletna Referencja Klas

Tailwind CSS is a utility-first CSS framework that lets you build designs directly in your markup. Instead of writing custom CSS, you apply pre-built utility classes. This complete Tailwind CSS cheat sheet covers every major category of classes with their CSS output, so you can quickly look up any utility you need.

Why Tailwind CSS and Why a Cheat Sheet?

Tailwind CSS has hundreds of utility classes. While the naming convention is intuitive, having a quick-reference cheat sheet saves time and boosts productivity. This guide organizes all essential classes by category with exact CSS output.

Spacing: Padding & Margin

Tailwind uses a consistent spacing scale. The number after p- or m- maps to a rem value (multiply by 0.25rem). Negative margins use -m- prefix.

Directional Padding & Margin

<!-- Spacing examples -->
<div class="p-4">padding 1rem all sides</div>
<div class="px-6 py-3">horizontal 1.5rem, vertical 0.75rem</div>
<div class="mt-8 mb-4">top margin 2rem, bottom margin 1rem</div>
<div class="mx-auto max-w-lg">centered container</div>
<div class="-mt-4">negative top margin (overlap)</div>
<div class="space-x-4">children spaced 1rem horizontally</div>
<div class="space-y-2">children spaced 0.5rem vertically</div>

Typography

Tailwind provides utilities for font size, weight, line height, letter spacing, text alignment, and text color.

Tips & Advanced Usage

Power-user features for when the built-in utilities are not enough.

Arbitrary Values

Use square brackets to specify any custom value:

<!-- Arbitrary values with square brackets -->
<div class="w-[120px]">width: 120px</div>
<div class="h-[calc(100vh-80px)]">height: calc(100vh - 80px)</div>
<div class="bg-[#1a2b3c]">background: #1a2b3c</div>
<div class="text-[22px]">font-size: 22px</div>
<div class="grid-cols-[200px_1fr_200px]">custom grid template</div>
<div class="p-[clamp(1rem,3vw,3rem)]">responsive clamp padding</div>
<div class="text-[color:var(--brand)]">CSS variable color</div>
<div class="top-[var(--header-h)]">CSS variable position</div>

Important Modifier

Prefix any utility with ! to add !important:

<!-- Important modifier with ! prefix -->
<div class="!p-4">padding: 1rem !important</div>
<div class="!mt-0">margin-top: 0 !important</div>
<div class="!text-red-500">color: #ef4444 !important</div>

<!-- Useful for overriding third-party styles -->
<div class="external-widget !bg-transparent !border-none">
  Override library styles
</div>

@apply Directive

Extract repeated utility patterns into custom CSS classes:

/* In your CSS file — use @apply to extract components */
.btn {
  @apply px-4 py-2 rounded-lg font-semibold transition-colors duration-200;
}

.btn-primary {
  @apply btn bg-blue-500 text-white hover:bg-blue-700;
}

.btn-secondary {
  @apply btn bg-gray-200 text-gray-800 hover:bg-gray-300;
}

.input {
  @apply w-full px-3 py-2 border border-gray-300 rounded-md
         focus:outline-none focus:ring-2 focus:ring-blue-500
         focus:border-transparent;
}

.card {
  @apply bg-white dark:bg-gray-800 rounded-xl shadow-md p-6
         hover:shadow-lg transition-shadow duration-300;
}

/* Note: Tailwind recommends using utilities directly in HTML
   and only extracting with @apply for truly repeated patterns. */
