## Style Objects

styled-components optionally supports writing CSS as JavaScript objects instead of strings. This is particularly useful when you have existing style objects and want to gradually move to styled-components.

```react
// Static object
const Box = styled.div<{ $background?: string; }>({
  background: '#BF4F74',
  height: '50px',
  width: '50px'
});

// Adapting based on props
const PropsBox = styled.div(props => ({
  background: props.$background,
  height: '50px',
  width: '50px'
}));

render(
  <div>
    <Box />
    <PropsBox $background="blue" />
  </div>
);
```
