# --description--

By manipulating different selectors and properties, you can make interesting shapes. One of the easier ones to try is a crescent moon shape. For this challenge you need to work with the `box-shadow` property that sets the shadow of an element, along with the `border-radius` property that controls the roundness of the element's corners.

You will create a round, transparent object with a crisp shadow that is slightly offset to the side - the shadow is actually going to be the moon shape you see.

In order to create a round object, the `border-radius` property should be set to a value of 50%.

You may recall from an earlier challenge that the `box-shadow` property takes values for `offset-x`, `offset-y`, `blur-radius`, `spread-radius` and a color value in that order. The `blur-radius` and `spread-radius` values are optional.

# --instructions--

Manipulate the square element in the editor to create the moon shape. First, change the `background-color` to transparent, then set the `border-radius` property to 50% to make the circular shape. Finally, change the `box-shadow` property to set the `offset-x` to 25px, the `offset-y` to 10px, `blur-radius` to 0, `spread-radius` to 0, and color to blue.

# --hints--

The value of the `background-color` property should be set to `transparent`.

```js
assert(code.match(/background-color:\s*?transparent;/gi));
```

The value of the `border-radius` property should be set to `50%`.

```js
assert(code.match(/border-radius:\s*?50%;/gi));
```

The value of the `box-shadow` property should be set to 25px for `offset-x`, 10px for `offset-y`, 0 for `blur-radius`, 0 for `spread-radius`, and finally blue for the color.

```js
assert(
  code.match(/box-shadow:\s*?25px\s+?10px\s+?0(px)?\s+?0(px)?\s+?blue\s*?;/gi)
);
```
