# --description--

La unidad `rem` significa `root em`, y es relativa al tamaño de fuente del elemento `html`.

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--

Debe tener un selector `.small-text`.

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

El selector `.small-text` debe tener una propiedad `font-size` establecida en `0.85rem`.

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