# --description--

The `rem` unit stands for `root em`, and is relative to the font size of the `html` element.

Create a `.small-text` selector and set the `font-size` to `0.85rem`, which would calculate to roughly `13.6px` (remember that you set your `html` to have a `font-size` of `16px`).

# --hints--

You should have an `.small-text` selector.

```js
assert(new __helpers.CSSHelp(document).getStyle('.small-text'));
```

Your `.small-text` selector should have a `font-size` property set to `0.85rem`.

```js
assert(new __helpers.CSSHelp(document).getStyle('.small-text')?.fontSize === '0.85rem');
```
