Creates a circular shape with pure CSS.

• Use border-radius: 50% to curve the borders of the element to create a circle.
• Since a circle has the same radius at any given point, the width and height must be the same. Differing values will create an ellipse.

<div class="circle"></div>

.circle {
  border-radius: 50%;
  width: 32px;
  height: 32px;
  background: #9C27B0;
}
