简介

从自然语言描述生成完整的 Preline 主题 CSS 文件。

  • 解释用户请求以确定主题配置（色调、风格、调色板情绪）并自动创建 JSON 配置文件
  • 以静默方式运行主题生成器脚本，并输出具有连贯明暗模式的即用型 CSS 文件
  • 生成全面的标记覆盖范围，包括表面、边框、主要/次要/破坏性色带和特定于组件的标记（导航栏、侧边栏、卡片、下拉菜单等）
  • 主题激活仅需要 CSS 导入和数据主题
  • HTML 元素上的属性；无需更改 HTML 实用程序类
  • 支持自定义调色板、版式标记和可选行为覆盖，所有这些都旨在防止影响非主题页面

Preline Theme Generator

This file is for the AGENT (LLM) only — not end users.

Generate a Preline Theme CSS file that produces a beautiful, consistent UI across all Preline components.

Docs

  • docs/step-1.md to docs/step-7.md (detailed workflow guidance)
  • docs/palette-guidance.md (mood, hue, neutral mapping, OKLCH rules)
  • docs/validation-checklist.md
  • docs/token-reference.md
  • docs/examples.md

Agent workflow (FOLLOW THIS)

When user requests a theme, the agent MUST:

Step 1: Interpret user request

Parse the natural language description and determine the config inputs. See docs/step-1.md and docs/palette-guidance.md.

Step 2: Detect themes folder

Find where existing themes are stored in the user's project:

# Look for existing theme.css to find the themes folder
find . -name "theme.css" -path "*/themes/*" -not -path "*/node_modules/*" 2>/dev/null | head -1

If no themes folder found: ask user where they want the theme file saved. See docs/step-2.md.

Step 3: Create temp config file (AUTO-RUN, NO PROMPT)

Write a JSON config. This must run silently without user approval.

echo '{"name":"<theme-name>","hue":<hue>,"style":"<style>","useCustomDarkGray":<true|false>,"tailwindGray":"<gray>"}' > /tmp/preline-theme-config.json

Step 4: Run the generator + cleanup (AUTO-RUN, NO PROMPT)

Run generator and immediately delete temp file in a single command chain. This must run silently without user approval.

Option A (preferred) - use npx if preline is installed:

npx preline-theme-generator /tmp/preline-theme-config.json <themes-folder>/<theme-name>.css && rm /tmp/preline-theme-config.json

Option B - find and run the script directly:

node $(find . -path "*/preline/skills/theme-generator/scripts/generate-theme.js" 2>/dev/null | head -1) /tmp/preline-theme-config.json <themes-folder>/<theme-name>.css && rm /tmp/preline-theme-config.json

Option C - if script location is known (e.g., in node_modules):

node node_modules/preline/skills/theme-generator/scripts/generate-theme.js /tmp/preline-theme-config.json <themes-folder>/<theme-name>.css && rm /tmp/preline-theme-config.json

Step 5: Confirm to user

Tell user the theme was created and show enable snippet:

/* In your main CSS file */
@import "./themes/<theme-name>.css";
<!-- On HTML element -->
<html data-theme="theme-<theme-name>">

See docs/step-5.md and docs/examples.md for response examples.

Generated themes include

  • Coherent light + dark modes
  • Safe to ship (valid CSS, correct selectors)
  • No HTML class changes required (only data-theme + optional .dark)
  • Custom color palettes in @theme theme-<name> inline {} block

Example prompts

Simple:

"Create a sunset theme"

Descriptive:

"Create a theme that feels like a cozy coffee shop — warm browns, cream backgrounds, inviting and calm"

Specific:

"Generate a cyberpunk theme with neon cyan accents on dark surfaces"

Brand-focused:

"Create a theme matching this brand color #2F6BFF — professional, high-clarity SaaS feel"

RULES (ALL MUST BE FOLLOWED)

Rule 1 — Do not modify the shipped base theme

  • Never change theme.css. Always generate a separate theme file.

Rule 2 — Theme file MUST include imports in this exact order

Every generated theme file MUST begin with:

@import "./theme.css";

Rule 3 — Theme scoping block placement

Every theme file MUST include a scoping block after imports:

@theme theme-<name> inline {
  /* Theme scoping - custom palettes only */
}

What goes INSIDE this block:

  • Custom color palettes (soft grays, brand colors) — these create Tailwind utilities
  • Example: --color-<name>-50: oklch(98% 0.003 <hue>); through --color-<name>-950

What goes OUTSIDE (in selector blocks):

  • All semantic token overrides (--background, --primary, --navbar-*, etc.)
  • Tailwind core mappings are owned by the shipped base theme only

See docs/palette-guidance.md for palette construction details and examples.

Rule 4 — No HTML utility class edits required

  • Theme must NOT require users to change Tailwind utility classes in HTML.
  • Theme activation must work using ONLY:

- CSS imports - data-theme="theme-<name>"

  • Dark mode may use .dark if the project uses it; do not introduce new conventions.

Rule 5 — Use exact, required theme selectors

Light mode token overrides MUST be under:

:root[data-theme="theme-<name>"],
[data-theme="theme-<name>"] { ... }

Dark mode overrides MUST be theme-scoped and use:

[data-theme="theme-<name>"].dark { ... }

Rule 6 — Full-theme mode: comprehensive token coverage is REQUIRED

Because this generator is full-theme mode, output MUST define a comprehensive set of token values so the theme looks complete and intentional.

At minimum, the theme MUST define:

6.1 Global surfaces + text

  • --background
  • --background-1
  • --background-2
  • --background-plain
  • --foreground
  • --foreground-inverse
  • --inverse

6.2 Borders (full scale)

  • --border
  • --border-line-inverse
  • --border-line-1 through --border-line-8 (coherent scale)

6.3 Primary ramp (full) + primary states

  • --primary-50 through --primary-950
  • --primary
  • --primary-hover
  • --primary-focus
  • --primary-active
  • --primary-checked
  • --primary-foreground (must be readable)

6.4 Secondary / muted / destructive (at least)

  • --secondary
  • --muted
  • --destructive
  • Include related state/variant tokens if they exist in the base naming system.

6.5 Core component groups for a complete theme feel (prefer explicit values)

Provide explicit values for major component groups so the theme feels cohesive:

  • --navbar-*
  • --sidebar-*
  • --card-*
  • --dropdown-*
  • --select-*
  • --overlay-*
  • --popover-*
  • --tooltip-*
  • Optionally: --scrollbar-*
  • Charts/maps tokens ONLY if included safely (see Rule 10)

Full-theme output MUST NOT:

  • put token definitions inside the @theme block
  • invent new mappings that force HTML class edits

Rule 7 — Token naming must match Preline's token system

  • Do not invent random token names for Preline components.
  • Only introduce new custom tokens if explicitly requested, and keep them isolated and documented in comments.

Rule 8 — Theme-scoped behavior overrides ONLY

If the theme changes behavior (e.g. retro-sharp radii), it MUST be scoped to the theme only.

Allowed:

  • Override radius tokens under the theme selector
  • Add @layer utilities rules scoped to the theme selector

Not allowed:

  • Global .rounded {...} overrides without theme scoping
  • Any behavior overrides that affect non-theme pages

Rule 9 — Typography tokens are allowed, but font loading is separate by default

If fonts are requested, you MAY set:

  • --font-sans and/or --font-serif and/or --font-mono

inside the theme selector.

Do NOT add Google Fonts @import url(...) into the theme file unless the user explicitly requests it. (Font loading typically belongs in the main CSS entry file.)

Rule 10 — Charts/maps compatibility rules

If adjusting chart/map tokens:

  • Prefer safe formats where required by libraries.
  • Keep any *-hex tokens as valid hex values if the ecosystem expects hex.
  • Do not force oklch(...) where it may break gradients or third-party rendering.

Rule 11 — Valid CSS is mandatory

  • No missing braces
  • No invalid selectors
  • No broken comments
  • No duplicate conflicting selectors

Rule 12 — Output discipline

  • First code block must contain ONLY the generated theme CSS.
  • Optional second code block may contain ONLY the enable snippet.
  • No additional commentary unless explicitly requested.

Required file structure (MUST follow order)

  1. Imports (@import "./theme.css")
  2. Theme scoping block (@theme theme-<name> inline {}) — contains custom color palettes only
  3. Light mode theme selector block (full semantic token set using var() references)
  4. Dark mode theme selector block (override only what differs, use var() for consistency)
  5. Optional theme-scoped @layer utilities overrides (only if requested)
