Kolibry

Fonts

While you can use HTML and CSS to custom the fonts and style for your slides as you want, Kolibry also provides a convenient way to use them effortlessly.

In your frontmatter, configure as following

---
fonts:
  # basically the text
  sans: 'Robot'
  # use with `font-serif` css class from UnoCSS
  serif: 'Robot Slab'
  # for code blocks, inline code, etc.
  mono: 'Fira Code'
---

And that's all.

Fonts will be imported automatically from Google Fonts. That means you can use any fonts available on Google Fonts directly.

Local Fonts

By default, Kolibry assumes all the fonts specified via fonts configurations come from Google Fonts. If you want to use local fonts, specify the fonts.local to opt-out the auto-importing.

---
fonts:
  # like font-family in css, you can use `,` to separate multiple fonts for fallback
  sans: 'Helvetica Neue,Robot'
  # mark 'Helvetica Neue' as local font
  local: 'Helvetica Neue'
---

Weights & Italic

By default, Kolibry imports three weights 200,400,600 for each font. You can configure them by:

---
fonts:
  sans: 'Robot'
  # default
  weights: '200,400,600'
  # import italic fonts, default `false`
  italic: false
---

This configuration applies to all web fonts. For more fine-grained controls of each font's weights, you will need to manually import them with HTML and CSS.

Fallback Fonts

For most of the scenarios, you only need to specify the "special font" and Kolibry will append the fallback fonts for you, for example:

---
fonts:
  sans: 'Robot'
  serif: 'Robot Slab'
  mono: 'Fira Code'
---

will result in

.font-sans {
  font-family: "Robot",ui-sans-serif,system-ui,-apple-system,BlinkMacSystemFont,"Segoe UI",Roboto,"Helvetica Neue",Arial,"Noto Sans",sans-serif,"Apple Color Emoji","Segoe UI Emoji","Segoe UI Symbol","Noto Color Emoji";
}
.font-serif {
  font-family: "Robot Slab",ui-serif,Georgia,Cambria,"Times New Roman",Times,serif;
}
.font-mono {
  font-family: "Fira Code",ui-monospace,SFMono-Regular,Menlo,Monaco,Consolas,"Liberation Mono","Courier New",monospace;
}

If you want to disable the fallback fonts, configure as following

---
fonts:
  mono: 'Fira Code, monospace'
  fallback: false
---

Providers

  • Options: google | none
  • Default: google

Currently, only Google Fonts is supported, we are planned to add more providers in the future. Specify to none will disable the auto-importing feature entirely and treat all the fonts local.

fonts:
  provider: 'none'
