Blockquote

Gunshot, thunder, sword rise. A scene of flowers and blood.

A quiet page can still carry a loud idea.

Blockquotes can contain emphasis, links, and inline code.

Callouts

Use a blockquote marker to add a structured note. Labels are case-insensitive, and [!tips] maps to the tip style. Add a title after the marker when the default label is not enough.

Add - to start closed, or + to start open. Both forms use native details controls, so their state works without client-side scripts:

Check this before publishing

This content stays quiet until the reader chooses to open it.

This note starts open

Custom titles preserve inline Markdown, including code and emphasis.

Horizontal rule

Code

Short blocks stay expanded:

const theme = 'serene'
console.log(`hello, ${theme}`)

Longer blocks get a collapse control in the theme UI:

// Sample multi-line snippet for collapse testing
export type NavItem = { label: string; href: string }

export function isActive(pathname: string, href: string): boolean {
  if (href === '/') return pathname === '/'
  return pathname === href || pathname.startsWith(`${href}/`)
}

export function formatTitle(
  pageTitle: string | undefined,
  siteTitle: string,
  delimiter: string
): string {
  if (!pageTitle) return siteTitle
  return `${pageTitle} ${delimiter} ${siteTitle}`
}

// padding lines so the block is long enough to collapse
const lines = Array.from({ length: 12 }, (_, i) => `line-${i + 1}`)
console.log(lines.join('\n'))

Math

Inline math uses single dollar signs, such as $E = mc^2$ .

Display math uses a double-dollar block:

\int_0^1 x^2\,dx = \frac{1}{3}

Keyboard and marks

Use Ctrl + K (or ⌘K) for search. Highlighted text uses the theme mark style when available.
