—> at lesson Applied Visual Design —> Create a Graphic using CSS (38/52)

Trying to finish/run code for the lesson, even if I set the border-radius to 50px as requested, the system seems not to record the change as it doesnt “pass” me on the border-radius requirement. everything is just fine.

  **Your code so far**

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

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

You need to read and follow the instructions carefully:

… then set the border-radius property to 50% to make the circular shape.

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