## Description
<section id='description'>
When you create your variables in <code>:root</code> they will set the value of that variable for the whole page.
You can then over-write these variables by setting them again within a specific element.
</section>

## Instructions
<section id='instructions'>
Change the value of <code>--penguin-belly</code> to <code>white</code> in the <code>penguin</code> class.
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: The <code>penguin</code> class should reassign the <code>--penguin-belly</code> variable to <code>white</code>.
    testString: assert(code.match(/.penguin\s*?{[\s\S]*--penguin-belly\s*?:\s*?white\s*?;[\s\S]*}/gi));
