# --description--
Your `output.innerHTML` string will need a `span` element. Create that, and give it a `class` attribute set to the `surplusOrDeficit` variable, but lowercased.
When you need to lower case a string, you can use the <dfn>toLowerCase()</dfn> method. This method returns the calling string value converted to lower case.
Strings have a `.toLowerCase()` method that can help you with this. Do not give your `span` any text yet.
```js
const firstName = 'JESSICA';
console.log(firstName.toLowerCase()); // Output: jessica
```
