Scalar Themes


Scalar Themes provides a library of themes for all Scalar products and components. It also contains the base set of Scalar CSS variables and an associated Tailwind preset which leverages those variables.

To see a list of available themes, see the presets export.

CSS Layers

The themes package uses two CSS Layers to apply the theme styles

- scalar-base: A copy of the core Scalar CSS variables and default theme
- scalar-theme: Optionally overrides scalar-base with theme styles

Any styles added outside of these layers will override all the styles in the layers which allows you to extend or customize a theme.

Scoping

Because many Scalar applications are embedded into other websites the reset is scoped to the scalar-app class. This means you need to add this class to the root element of your application where you want the theme to apply. If you are using the themes in a standalone application, you can just add this class to the body element.

Installation

`bash
pnpm i @scalar/themes
`

$3

To import the basic theme styles into your project, you can just import style.css which imports the reset, scrollbars, and a copy of the base Scalar CSS variables and default theme.

`ts
import '@scalar/themes/styles.css'
`

To add a theme, you can import the theme from the presets directory.

`ts
import '@scalar/themes/presets/alternate.css'
`

$3

To use the themes package via JavaScript, you can use the getThemeStyles function from the package. The function will generate CSS style string which you can then add to the head of your document.

`ts
import { getThemeStyles } from '@scalar/themes'

const styles = getThemeStyles('alternate', { layer: 'scalar-theme' })
document.head.insertAdjacentHTML('beforeend', )
`

The function allows you to pass in a theme ID and an optional options object to configure the layer (default: scalar-theme) and whether to include the default fonts (default: true).

$3

To use the themes package with Tailwind, you first need to import the base styles either via CSS or JavaScript (see above).

Then you can use the tailwind config in your Tailwind CSS to expose the theme colors and variables. The Scalar Tailwind config already contains a preflight and copy of the base Tailwind theme so all you need to import from Tailwind is tailwindcss/utilities.css.

`css
@import "@scalar/themes/style.css"; / Theme Base Styles and Reset /
@import "@scalar/themes/tailwind.css"; / Tailwind Theme + Config /

@import "tailwindcss/utilities.css"; / Generate the Tailwind classes /
