Create a Graphic Using CSS --- new moon graphics

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-xoffset-yblur-radiusspread-radius and a color value in that order. The blur-radius and spread-radius values are optional.

 

The original code pattern as follows:

 

 

Exercises:

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.

  • First into a transparent blue background
  • Readjustment green shadow behind the box-shadow boundary radius, 50%
  • Finally, fine-tuning box-shadow, before practice done about this, did I have forgotten, so he looked at the effect of the adjustment under different values. The basic color of the new moon is to change from green to blue, blur the edges of change peaked, after experiencing it and then take a closer look

 

Practice Code:

<style>
  .center {
    position: absolute;
    margin: auto;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    width: 100px;
    height: 100px;
    background-color: transparent;
    border-radius: 50%;
    box-shadow: 25px 10px 0 0 blue;
  }

</style>
<div class="center"></div>

 

effect:
