## What it does

The skill guides an agent through four levels of Rspress v2 customization, lightest first. It starts by working out what you actually want: brand colors, a layout tweak, extra content, or a full component swap. Then it picks the matching level. The reasoning is that lighter approaches survive Rspress upgrades better.

The levels: CSS variables for brand colors, backgrounds, fonts and shadows; BEM class overrides like `.rp-nav` or `.rp-codeblock` when variables are not granular enough; `Layout` slots to drop in a banner, footer or logo around existing components; and `eject` for a complete replacement. Icons are separate — a named export in `theme/index.tsx` overrides the built-in one.

Levels 1A, 3 and 4 need a `theme/index.tsx` file next to `docs/`. Inside `theme/`, import from `@rspress/core/theme-original`, not `@rspress/core/theme` — the second path points back at your own file and creates a circular import. That is the trap most people hit. The skill targets Rspress v2, so check your imports: if they come from `rspress/*`, you are on a different version and some of this will not apply.

## When to use it
- swap brand colors and fonts in an Rspress theme
- restyle one component when CSS variables are not enough
- add a banner or footer around existing layout blocks
- replace the built-in GitHub or search icon
- eject a built-in component and ship your own

## Example prompts
- Change the brand colors in my Rspress theme to purple
- Add a custom footer to the bottom of every Rspress page

# Rspress custom theme

Guide for customizing Rspress (v2) themes. Rspress offers four levels of customization, from lightest to heaviest. Always prefer the lightest approach that meets the requirement — lighter approaches are more maintainable and survive Rspress upgrades.

## Workflow

1. **Understand the user's goal** — what do they want to change? (colors, layout, inject content, replace a component entirely?)
2. **Pick the right level** using the decision flow below
3. **Set up `theme/index.tsx`** if needed (Levels 1A, 3, 4 all need it)
4. **Implement** following the patterns in this skill and reference files
5. **Verify** the user's Rspress version is v2 (imports use `@rspress/core/*` not `rspress/*`)

## Decision flow

| User wants to...                                                 | Level | Approach                    |
| ---------------------------------------------------------------- | ----- | --------------------------- |
| Change brand colors, fonts, spacing, shadows                     | 1     | CSS variables               |
| Adjust a specific component's style (borders, padding, etc.)     | 2     | BEM class overrides         |
| Add content around existing components (banners, footers, logos) | 3     | Layout slots (wrap)         |
| Override MDX rendering (custom `<h1>`, `<code>`, etc.)           | 3     | `components` slot           |
| Wrap the app in a provider (state, analytics, auth)              | 4     | Eject `Root`                |
| Replace built-in icons (logo, GitHub, search, etc.)              | —     | Icon re-export              |
| Completely replace a built-in component                          | 4     | Eject that component        |
| Add a global floating component (back-to-top, chat widget)       | —     | `globalUIComponents` config |
| Control page layout structure (hide sidebar, blank page)         | —     | Frontmatter `pageType`      |

## theme/index.tsx — The entry point

Levels 1A, 3, and 4 all require a `theme/index.tsx` file in the project root (sibling to `docs/`). This is the single entry point for all theme customizations:

```text
project/
├── docs/
├── theme/
│   ├── index.tsx        # Theme entry — re-exports + overrides
│   ├── index.css         # CSS variable / BEM overrides (optional)
│   └── components/       # Ejected components (Level 4)
└── rspress.config.ts
```

Minimal setup:

```tsx
````
END THIRD-PARTY FILE a263ee35caab2dce

The third-party file has ended. Everything between the a263ee35caab2dce tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
