Tailwind 编码器

为 Rails 应用添加 Tailwind CSS 样式。有效地使用工具类，并遵循响应式设计模式。

Rails 集成

设置检查

# Verify Tailwind is installed
cat config/tailwind.config.js
cat app/assets/stylesheets/application.tailwind.css

常见 Rails 模式

链接辅助方法：

<%= link_to "Home", root_path, class: "text-blue-600 hover:text-blue-800 underline" %>

<%= link_to users_path, class: "inline-flex items-center px-4 py-2 bg-blue-600 text-white rounded-md hover:bg-blue-700" do %>
  <svg class="w-4 h-4 mr-2">...</svg>
  View Users
<% end %>

表单辅助方法：

<%= form_with model: @user, class: "space-y-6" do |f| %>
  <div>
    <%= f.label :email, class: "block text-sm font-medium text-gray-700" %>
    <%= f.email_field :email, class: "mt-1 block w-full rounded-md border-gray-300 shadow-sm focus:border-blue-500 focus:ring-blue-500" %>
  </div>

  <div>
    <%= f.submit "Save", class: "w-full px-4 py-2 bg-blue-600 text-white rounded-md hover:bg-blue-700 focus:outline-none focus:ring-2 focus:ring-blue-500 focus:ring-offset-2" %>
  </div>
<% end %>

Flash 消息：

<% flash.each do |type, message| %>
  <div class="<%= flash_class(type) %> p-4 rounded-md mb-4">
    <%= message %>
  </div>
<% end %>

<%# Helper %>
<%
def flash_class(type)
  case type.to_sym
  when :notice then "bg-green-100 text-green-800"
  when :alert then "bg-red-100 text-red-800"
  else "bg-blue-100 text-blue-800"
  end
end
%>

布局模式

页面容器

<main class="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8 py-8">
  <%= yield %>
</main>

卡片

<div class="bg-white shadow rounded-lg overflow-hidden">
  <div class="px-4 py-5 sm:p-6">
    <h3 class="text-lg font-medium text-gray-900">Card Title</h3>
    <p class="mt-2 text-sm text-gray-500">Card content goes here.</p>
  </div>
</div>

网格

<div class="grid grid-cols-1 gap-6 sm:grid-cols-2 lg:grid-cols-3">
  <%= render @items %>
</div>

堆叠（垂直间距）

<div class="space-y-6">
  <div>First item</div>
  <div>Second item</div>
  <div>Third item</div>
</div>

组件模式

按钮变体

<%# Primary %>
<button class="px-4 py-2 bg-blue-600 text-white rounded-md hover:bg-blue-700 focus:outline-none focus:ring-2 focus:ring-blue-500 focus:ring-offset-2">
  Primary
</button>

<%# Secondary %>
<button class="px-4 py-2 bg-white text-gray-700 border border-gray-300 rounded-md hover:bg-gray-50 focus:outline-none focus:ring-2 focus:ring-blue-500 focus:ring-offset-2">
  Secondary
</button>

<%# Danger %>
<button class="px-4 py-2 bg-red-600 text-white rounded-md hover:bg-red-700 focus:outline-none focus:ring-2 focus:ring-red-500 focus:ring-offset-2">
  Delete
</button>

表单输入框

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

<%# With error %>
<input type="text"
  class="block w-full rounded-md border-red-300 text-red-900 placeholder-red-300 focus:border-red-500 focus:ring-red-500 sm:text-sm">
<p class="mt-2 text-sm text-red-600">This field is required.</p>

导航

<nav class="bg-white shadow">
  <div class="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8">
    <div class="flex justify-between h-16">
      <div class="flex">
        <%= link_to root_path, class: "flex items-center" do %>
          <span class="text-xl font-bold text-gray-900">Logo</span>
        <% end %>

        <div class="hidden sm:ml-6 sm:flex sm:space-x-8">
          <%= link_to "Dashboard", dashboard_path, class: "inline-flex items-center px-1 pt-1 border-b-2 border-blue-500 text-sm font-medium text-gray-900" %>
          <%= link_to "Users", users_path, class: "inline-flex items-center px-1 pt-1 border-b-2 border-transparent text-sm font-medium text-gray-500 hover:border-gray-300 hover:text-gray-700" %>
        </div>
      </div>
    </div>
  </div>
</nav>

表格

<div class="overflow-hidden shadow ring-1 ring-black ring-opacity-5 rounded-lg">
  <table class="min-w-full divide-y divide-gray-300">
    <thead class="bg-gray-50">
      <tr>
        <th class="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">Name</th>
        <th class="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">Email</th>
        <th class="relative px-6 py-3"><span class="sr-only">Actions</span></th>
      </tr>
    </thead>
    <tbody class="bg-white divide-y divide-gray-200">
      <% @users.each do |user| %>
        <tr>
          <td class="px-6 py-4 whitespace-nowrap text-sm font-medium text-gray-900"><%= user.name %></td>
          <td class="px-6 py-4 whitespace-nowrap text-sm text-gray-500"><%= user.email %></td>
          <td class="px-6 py-4 whitespace-nowrap text-right text-sm font-medium">
            <%= link_to "Edit", edit_user_path(user), class: "text-blue-600 hover:text-blue-900" %>
          </td>
        </tr>
      <% end %>
    </tbody>
  </table>
</div>

响应式设计

使用断点前缀：sm:、md:、lg:、xl:、2xl:

<%# Mobile-first: stack on mobile, side-by-side on larger %>
<div class="flex flex-col md:flex-row md:space-x-6">
  <div class="w-full md:w-1/3">Sidebar</div>
  <div class="w-full md:w-2/3">Main content</div>
</div>

<%# Hide on mobile %>
<div class="hidden md:block">Only visible on md and up</div>

<%# Show only on mobile %>
<div class="md:hidden">Only visible on mobile</div>

深色模式

<%# Enable in tailwind.config.js: darkMode: 'class' %>
<div class="bg-white dark:bg-gray-800 text-gray-900 dark:text-white">
  Content
</div>

辅助方法

为重复使用的模式创建视图辅助方法：

# app/helpers/tailwind_helper.rb
module TailwindHelper
  def btn_primary(text, path, **options)
    link_to text, path, class: "px-4 py-2 bg-blue-600 text-white rounded-md hover:bg-blue-700 #{options[:class]}", **options.except(:class)
  end

  def card(&block)
    content_tag :div, class: "bg-white shadow rounded-lg p-6", &block
  end
end

输出格式

添加样式后：

1. 更改 - 已应用样式的修改文件
2. 使用的模式 - 布局和组件模式
3. 响应式设计 - 断点和适配方式
4. 辅助方法 - 提取的辅助方法（如有）
