Markdown Syntax

Slide Separators

Separate slides with --- padded by blank lines:

Content here

---

# Slide 2

More content

Frontmatter and Headmatter

Configure entire deck with headmatter (first YAML block):

Copy---

---

# Centered Slide

Content here

Code Blocks

Code with syntax highlighting:

Copy```ts
console.log('Hello, World!')
```

With line numbers:

Copy```ts {lines:true}
function greet(name: string) {
  console.log(`Hello, ${name}!`)
}
```

With line highlighting:

Copy```ts {2,4-6}
function calculate() {
  const x = 10  // highlighted
  const y = 20
  const sum = x + y  // highlighted
  const product = x * y  // highlighted
  const difference = x - y  // highlighted
  return sum
}
```

Presenter Notes

Add notes at the end of slides using comment blocks:

Copy# Slide Title

Content visible to audience

<!--

• Test export early for large presentations

Collaboration

• Version control slides.md and assets
• Document custom components
• Share themes via npm packages
• Use consistent formatting

Presenting

• Test presenter mode before presenting
• Prepare speaker notes
• Test all interactive features
• Have PDF backup ready

Troubleshooting

Build Issues

If build fails, try:

Copy# Clear cache
rm -rf node_modules/.vite

# Rebuild
slidev build

Export Issues

Missing content: Add wait time

Copyslidev export --wait 2000

Broken emojis: Install system fonts or use icon libraries

Large file size: Export specific slides or reduce image quality

Port Conflicts

Specify custom port:

Copyslidev --port 3333

Theme Not Loading

Ensure theme is installed:

Copypnpm add slidev-theme-NAME

And configured correctly in headmatter:

Copy---
theme: NAME

    Count: {{ count }}
  </button>
</template>
EOF

# Use in slides.md
# <Counter />

Theming Workflow

Copy# Install theme
pnpm add slidev-theme-seriph
