# --description--

Notice that the edges of the shadow are sharp. This is because there is an optional `blurRadius` value for the `box-shadow` property:

```css
box-shadow: offsetX offsetY blurRadius color;
```

If a `blurRadius` value isn't included, it defaults to `0` and produces sharp edges. The higher the value of `blurRadius`, the greater the blurring effect is.

In the `.green` CSS rule, add the `box-shadow` property with the values `5px` for `offsetX`, `5px` for `offsetY`, `5px` for `blurRadius`, and `green` for `color`.

# --hints--

Your `.green` CSS rule should have a `box-shadow` shorthand property and with the value `5px 5px 5px green`.

```js
assert.strictEqual(new __helpers.CSSHelp(document).getStyle('.green')?.boxShadow, 'green 5px 5px 5px');
```
