## CSS File Locations

## Dark Mode

Use `[data-theme='dark']` or `html[data-theme='dark']` selectors:

```css
[data-theme='dark'] .my-element {
    background: #21262d;
    color: #fff;
}
```

## Component Styling

React components have co-located CSS modules:

```
src/components/
├── Steps/
│   ├── index.js
│   └── index.module.css
├── ActionCard/
│   ├── index.js
│   └── index.module.css
```

Use `clsx` for conditional class names:

```jsx
import clsx from 'clsx';
import styles from './index.module.css';

<div className={clsx(styles.container, isActive && styles.active)} />
```
