## Description
Another way to add styling is to use the `style` property directly, like `output.style.width = '300px'`.
Add a `backgroundColor` style to `output` and set it equal to `'#FFF9C4'`.
The `calculate()` function is now finished!
## Instructions
## Tests
```yml
tests:
- text: See description above for instructions.
testString: assert( code.replace(/\s/g, '').match(/output\.style\.backgroundColor\=[\'\"\`]\#FFF9C4[\'\"\`]/) );
```
