The **theme** plugin provides CSS styling for SVG output:

<Example pattern="rendertest" part="test" caption="An example of the styles provided by this plugin" design={false} />

It uses the [`preRender`](/plugins#prerender) hook to do so.

<Note>

This plugin only applies to rendered SVG output. If you use our React component to display
patterns, you should style our component or use our [css-theme](/reference/packages/css-theme) package.

</Note>

## Installation

```bash
npm install @freesewing/plugin-theme
```

## Usage

Like all [build-time plugins](/guides/plugins/#build-time-plugins), you load them 
by passing them to the [`freesewing.Design`](/reference/api#design) constructor:

```js
import Aaron from "@freesewing/aaron";
import theme from "@freesewing/plugin-theme";

const myAaron = new Aaron()
  .use(theme);
```
