tailwind（Tailwind CSS 样式）

Tailwind CSS Expert

Expert Tailwind CSS patterns for building modern, responsive interfaces.

Core Principles

1. Utility-first: Compose designs directly in markup using utility classes
2. Responsive by default: Mobile-first with sm:, md:, lg:, xl:, 2xl: prefixes
3. Consistent spacing: Use the spacing scale (4, 8, 12, 16, 20, 24, 32, 40, 48, 64)
4. Design tokens: Leverage the default theme or extend it consistently

Common Patterns

Layout

<!-- Flexbox centering -->
<div class="flex items-center justify-center">

<!-- Grid layout -->
<div class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">

<!-- Container with padding -->
<div class="container mx-auto px-4 sm:px-6 lg:px-8">

Typography

<!-- Headings -->
<h1 class="text-3xl font-bold tracking-tight text-gray-900">
<h2 class="text-2xl font-semibold text-gray-800">
<p class="text-base text-gray-600 leading-relaxed">

<!-- Truncation -->
<p class="truncate">  <!-- Single line -->
<p class="line-clamp-3">  <!-- Multi-line -->

Buttons

<!-- Primary -->
<button class="px-4 py-2 bg-blue-600 text-white font-medium rounded-lg hover:bg-blue-700 focus:outline-none focus:ring-2 focus:ring-blue-500 focus:ring-offset-2 transition-colors">

Cards

<div class="bg-white rounded-xl shadow-sm border border-gray-200 p-6">

<input type="email" class="mt-1 block w-full rounded-md border-gray-300 shadow-sm focus:border-blue-500 focus:ring-blue-500 sm:text-sm">

Responsive Design

<!-- Stack on mobile, side-by-side on larger screens -->
<div class="flex flex-col sm:flex-row gap-4">

<!-- Hide on mobile, show on desktop -->
<div class="hidden lg:block">

<!-- Different padding at breakpoints -->
<div class="p-4 sm:p-6 lg:p-8">

Dark Mode

<div class="bg-white dark:bg-gray-900 text-gray-900 dark:text-white">

States

<!-- Hover, focus, active -->
<button class="hover:bg-blue-700 focus:ring-2 active:bg-blue-800">

<!-- Disabled -->
<button class="disabled:opacity-50 disabled:cursor-not-allowed">

<!-- Group hover -->
<div class="group">
  <span class="group-hover:text-blue-600">
</div>

Animation

<!-- Transitions -->
<div class="transition-all duration-200 ease-in-out">

<!-- Built-in animations -->
<div class="animate-spin">
<div class="animate-pulse">
<div class="animate-bounce">

Best Practices

1. Extract repeated patterns into components or partials
2. Use @apply sparingly in CSS files for complex repeated patterns
3. Prefer semantic HTML with utility classes over <div> soup
4. Use the official Tailwind CSS IntelliSense extension
5. Customize theme in tailwind.config.js rather than arbitrary values
