## About

# Slidev Themes

This skill covers using, customizing, and creating themes for Slidev presentations. Themes provide consistent styling, layouts, and components across your slides.

## When to Use This Skill

- Choosing a theme for your presentation
- Customizing theme colors and styles
- Ejecting and modifying themes
- Creating your own theme
- Understanding theme structure

## Using Themes

### Setting a Theme

In your first slide's frontmatter:

```yaml
---
theme: seriph
---
```

### Theme Name Conventions

- Official themes: Use short name (`seriph`, `default`)
- NPM packages: Use full name (`slidev-theme-custom`)
- Local themes: Use path (`./my-theme`)

### Auto-Installation

Slidev automatically prompts to install missing themes:

```bash
? The theme "seriph" was not found, do you want to install it now? (Y/n)
```

### Manual Installation

```bash
npm install slidev-theme-seriph
```

---
theme: default
---
```

### Installing Community Themes

```bash
npm install slidev-theme-penguin
```

```yaml

```

## Theme Configuration

### themeConfig

Pass configuration to themes:

```yaml
---
theme: seriph
themeConfig:
  primary: '#5d8392'
  secondary: '#8b5cf6'
  tertiary: '#3b82f6'
  darkBg: '#1a1a2e'
  lightBg: '#f8fafc'
---
```

### Available Options

Each theme defines its own options. Check theme documentation for:
- Color customization
- Font settings
- Layout options
- Component variants

### Common themeConfig Options

```yaml
themeConfig:
  # Colors
  primary: '#3b82f6'
  secondary: '#10b981'
  background: '#ffffff'
  text: '#1e293b'

  # Typography
  fontFamily: 'Inter'
  fontSize: '16px'

  # Layout
  padding: '2rem'
```

## Color Schema

### Auto (Default)

```yaml
---
colorSchema: auto
---
```

Follows system preference.

### Force Light

```yaml
---
colorSchema: light
---
```

### Force Dark

```yaml
---
colorSchema: dark
---
```

## Ejecting Themes

### Why Eject?

To fully customize a theme's source code:
- Modify layouts
- Change components
- Deep style customization

### How to Eject

```bash
slidev theme eject
```

This copies the theme to your project's local files.

### Ejected Structure

```
my-presentation/
├── slides.md
├── theme/
│   ├── layouts/
│   │   ├── default.vue
│   │   ├── cover.vue
│   │   └── ...

│   ├── styles/
│   │   └── index.css
│   └── setup/
│       └── main.ts
└── package.json
```

### Using Ejected Theme

```yaml
---
theme: ./theme

.cover {
  display: flex;

}

```

/* styles/index.css */
:root {
  --slidev-theme-primary: #3b82f6;
  --slidev-theme-secondary: #10b981;
  --slidev-theme-text: #1e293b;
  --slidev-theme-background: #ffffff;
}

}
```

  border-radius: 0.5rem;
  margin: 1rem 0;
}

  color: white;
}

.variant-secondary {
  background: var(--slidev-theme-secondary);
  color: white;
}

```

## Theme with Config

### Accepting Configuration

```vue

import { useSlideContext } from '@slidev/client'

const { $slidev } = useSlideContext()
const primaryColor = $slidev.themeConfigs?.primary || '#3b82f6'

  
    
  

```

### Default Config

In `setup/main.ts`:

```typescript
import { defineAppSetup } from '@slidev/types'

export default defineAppSetup(({ app }) => {
  app.provide('themeDefaults', {
    primary: '#3b82f6',
    secondary: '#10b981',
  })
})
```

## Publishing Themes

### Prepare for NPM

1. Ensure `package.json` has correct fields
2. Add README with usage instructions
3. Include screenshots

### Publish

```bash
npm publish
```

### Submit to Gallery

Open a PR to Slidev's theme gallery repository.

## Theme Best Practices

### 1. Support Both Color Schemes

```css
/* Light mode */
.slidev-layout {
  background: #ffffff;
  color: #1e293b;
}

/* Dark mode */
.dark .slidev-layout {
  background: #0f172a;
  color: #f1f5f9;
}
```

### 2. Use CSS Variables

```css
:root {
  --theme-primary: #3b82f6;
}

.primary {
  color: var(--theme-primary);
}
```

### 3. Provide Common Layouts

Essential layouts:
- `default`
- `cover`
- `center`
- `two-cols`
- `section`
- `end`

### 4. Document Configuration

README should include:
- Available themeConfig options
- Example usage
- Screenshots
- Layout descriptions

### 5. Test Thoroughly

- Test all layouts
- Test light and dark modes
- Test with real content
- Test export to PDF

## Output Format

When configuring themes:

```yaml
---
theme: [theme-name]
colorSchema: [auto|light|dark]
themeConfig:
  primary: '[color]'
  secondary: '[color]'
  [other options specific to theme]
---
```

**THEME SELECTION:**
- Chosen theme: [name]
- Reason: [why this theme fits]

**CUSTOMIZATION:**
- Primary color: [hex]
- Secondary color: [hex]
- Custom options: [list]

**ADDITIONAL FILES (if ejected):**
- layouts/[modified].vue
- styles/index.css
