Individual skill

sprucecss

Build and style web interfaces with Spruce CSS v3, the Sass-based CSS framework. Use when a project depends on the `sprucecss` npm package, imports `sprucecss/scss/spruce`, uses classes like `.btn`, `.form-control`, `.form-check` or `.table`, or when the user asks for Spruce CSS markup, Sass configuration, components, dark mode or design styles.

# Spruce CSS

Spruce CSS is a small, Sass-first framework. It styles native elements (typography, tables, forms, `details`, `dialog`, `progress`) with a few classes, and gives you **variables, mixins and functions** to write your own components. It has no grid system and only a handful of utility classes on purpose: write semantic HTML and component SCSS.

Docs: https://sprucecss.com/docs/ · Components: https://sprucecss.com/ui/

## Setup

```shell
npm install sprucecss
```

Configure Spruce on the **first** `@use` (Sass only allows configuration once), then generate the styles once:
