使用前

过去，为LLM代理手动设计和调整Preline主题CSS文件是一项耗时且容易出错的任务。开发者需要深入理解CSS样式规则，反复试验以确保UI的美观和一致性，这大大拖慢了开发进度。

使用后

借助Preline主题生成器，现在可以为LLM代理快速生成符合设计规范的Preline主题CSS文件。它自动化了样式创建过程，确保了UI的视觉美观和跨平台的统一性，显著提升了开发效率和用户体验。

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)

  • Imports (@import "./theme.css")

  • Theme scoping block (@theme theme-<name> inline { }) — contains custom color palettes only

  • Light mode theme selector block (full semantic token set using var() references)

  • Dark mode theme selector block (override only what differs, use var() for consistency)

  • Optional theme-scoped @layer utilities overrides (only if requested)
