What is tailwind-css-patterns?

A guide to Tailwind CSS, a styling framework that applies small utility classes directly to HTML or component markup.

Use it to style React, Vue, Svelte, or HTML components, build mobile-first layouts, create dark-mode interfaces, and define design-system utilities.

It helps organize responsive layouts and visual styles without repeatedly writing custom CSS for common spacing, typography, colors, flexbox, or grid needs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00062	$0.05171
Opus 5	$0.00031	$0.02586
Sonnet 5	$0.00012	$0.01034
Haiku 4.5	$0.00006	$0.00517

Security

Grade A, and why

tailwind-css-patterns scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Tailwind CSS Development Patterns

Source: ui-skills.com.

Expert guide for building modern, responsive user interfaces with Tailwind CSS utility-first framework. Covers v4.1+ features including CSS-first configuration, custom utilities, and enhanced developer experience.

When to Use

Styling React/HTML components with utility classes
Building responsive layouts with breakpoints
Implementing flexbox and grid layouts
Managing spacing, colors, and typography
Creating custom design systems
Optimizing for mobile-first design
Building dark mode interfaces

Core Concepts

Utility-First Approach

Apply styles directly in markup using utility classes:

<button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
  Click me
</button>

Responsive Design

Mobile-first breakpoints with prefixes:

<div class="w-full md:w-1/2 lg:w-1/3">
  <!-- Full width on mobile, half on tablet, third on desktop -->
</div>

Breakpoint prefixes:

sm: - 640px and above
md: - 768px and above
lg: - 1024px and above
xl: - 1280px and above
2xl: - 1536px and above

Layout Utilities

Flexbox Layouts

Basic flex container:

<div class="flex items-center justify-between">
  <div>Left</div>
  <div>Center</div>
  <div>Right</div>
</div>

Responsive flex direction:

<div class="flex flex-col md:flex-row gap-4">
  <div class="flex-1">Item 1</div>
  <div class="flex-1">Item 2</div>
  <div class="flex-1">Item 3</div>
</div>

Common flex patterns:

<!-- Center content -->
<div class="flex items-center justify-center min-h-screen">
  <div>Centered Content</div>
</div>

<!-- Space between items -->
<div class="flex justify-between items-center">
  <span>Left</span>
  <span>Right</span>
</div>

<!-- Vertical stack with gap -->
<div class="flex flex-col gap-4">
  <div>Item 1</div>
  <div>Item 2</div>
</div>

Grid Layouts

Basic grid:

<div class="grid grid-cols-3 gap-4">
  <div>Column 1</div>
  <div>Column 2</div>
  <div>Column 3</div>
</div>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
