CSS como usar o Circle
January 04, 2020
Creates a circle shape with pure CSS.
<div class="circle"></div>.circle {
  border-radius: 50%;
  width: 2rem;
  height: 2rem;
  background: #333;
}Explanation
border-radius: 50%curves the borders of an element to create a circle.- Since a circle has the same radius at any given point, the 
widthandheightmust be the same. Differing values will create an ellipse.
