## 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.
## Tests
```yml
tests:
- text: The value of the background-color
property should be set to transparent
.
testString: assert(code.match(/background-color:\s*?transparent;/gi), 'The value of the background-color
property should be set to transparent
.');
- text: The value of the border-radius
property should be set to 50%
.
testString: assert(code.match(/border-radius:\s*?50%;/gi), 'The value of the border-radius
property should be set to 50%
.');
- text: 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.
testString: assert(code.match(/box-shadow:\s*?25px\s+?10px\s+?0(px)?\s+?0(px)?\s+?blue\s*?;/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.');
```
