## Styling

The calendar uses styled-components for styling. You can customize the appearance by:

1. Using the built-in props
2. Extending the styled components
3. Wrapping components with custom styled containers

Example of custom styling:

```tsx
import styled from 'styled-components';
import { Year } from './components/calendar/Year';

const CustomCalendarContainer = styled.div`
  padding: 2rem;
  background: #fafafa;
  
  // Custom styles for the calendar
  .month-title {
    color: #1a73e8;
  }
`;

function App() {
  return (
    <CustomCalendarContainer>
      <Year 
        year={2024}
        dayHeaderStyle="tiny"
      />
    </CustomCalendarContainer>
  );
}
```

## Header Styles

- **expanded**: Full day names (e.g., "MONDAY")
- **compacted**: Three-letter day names (e.g., "MON")
- **tiny**: Single letter day names (e.g., "M")
- **none**: No day headers, only numbers

## Month Cutoff Options

- **dimmed**: Show days from other months with reduced opacity
- **truncate**: Hide days from other months
- **undefined**: Show all days normally

## Browser Support
