Theming

mdx-deck uses emotion for styling, making practically any part of the presentation themeable.

Built-in Themes

mdx-deck includes several built-in themes to change the look and feel of the presentation. Export theme from your MDX file to enable a theme.

export { dark as theme } from 'mdx-deck/themes'

# Dark Theme

View the List of Themes.

Custom Themes

A custom theme can be provided by exporting theme from the MDX file.

export { default as theme } from './theme'

# Hello

The theme should be an object with fields for fonts, colors, and CSS for individual components.

// Example theme.js
export default {
  // add a custom font
  font: 'Roboto, sans-serif',
  // custom colors
  colors: {
    text: '#f0f',
    background: 'black',
  },
}

Composing Themes

Multiple themes can be used together. For example, this allows the use of a syntax highlighting theme, along with a color theme, and a separate typography theme.

To compose themes together export a themes array instead of a single theme.

import { syntaxHighlighter } from 'mdx-deck/themes'
import customTheme from './theme'

export const themes = [syntaxHighlighter, customTheme]

# Cool. :sunglasses:

Please note that themes are deep merged together and the last theme specified will override fields from themes before it.

Google Fonts

Themes can specify a googleFont field to automatically add a <link> tag to the document head. Alternatively, use the <Head /> component to add a custom <link> tag.

Syntax Highlighting

By default fenced code blocks do not include any syntax highlighting. Themes can provide a set of custom MDX components, including a replacement for the default code component that can add syntax highlighting with libraries like react-syntax-highlighter.

MDX Deck includes two themes for adding syntax highlighting with react-syntax-highlighter: syntaxHighlighter and syntaxHighlighterPrism.

Since MDX supports using React components inline, you can also import a syntax highlighting component directly, if you prefer.

Styling Elements

Each element can be styled with a theme. Add a style object (or string) to the theme to target specific elements.

// example theme
export default {
  h1: {
    textTransform: 'uppercase',
    letterSpacing: '0.1em',
  },
  blockquote: {
    fontStyle: 'italic',
  },
}
