Styling your Components

UnoCSS

UnoCSS is an on-demand utility CSS library that integrates seamlessly with Solid as a Vite plugin.

Install Vite plugin

To get started with UnoCSS in your Solid app:

Import Vite plugin

After installation, open your vite.config.js or vite.config.ts. The default Solid Vite configuration looks like this:

import { defineConfig } from "vite";
import solidPlugin from "vite-plugin-solid";

export default defineConfig({
  plugins: [solidPlugin()],
  server: {
    port: 3000,
  },
  build: {
    target: "esnext",
  },
});

Now, import unocssPlugin from "unocss/vite" and add it to the plugins array:

import { defineConfig } from "vite";
import unocssPlugin from "unocss/vite";
import solidPlugin from "vite-plugin-solid";

export default defineConfig({
  plugins: [unocssPlugin(), solidPlugin()],
  server: {
    port: 3000,
  },
  build: {
    target: "esnext",
  },
});

Ensure that unocssPlugin is ordered before solidPlugin to prevent certain edge cases.

Import UnoCSS

In your root index.jsx or index.tsx file, import UnoCSS:

/* @refresh reload */
import "uno.css"
import { render } from "solid-js/web"
import "./index.css"
import App from "./App"

render(() => <App />, document.getElementById('root') as HTMLElement);

Alternatively, you can use the alias import "virtual:uno.css":

/* @refresh reload */
import "virtual:uno.css"
import { render } from "solid-js/web"
import "./index.css"
import App from "./App"

render(() => <App />, document.getElementById('root') as HTMLElement);
