Solved this by using CSS transform property:

You can refer to this JS fiddle link for below output: http://jsfiddle.net/suprabhasupi/74b1ptne/

div {
  border-radius: 50%;
  /* border: 1px solid red; */
}

.circle1 {
  position: relative;
  width: 300px;
  height: 300px;
  background-color: red;
}

.circle2 {
  transform: translate(25%, 25%);
  width: 200px;
  height: 200px;
  background-color: green;
}

.circle3 {
   transform: translate(48%, 46%);
  width: 100px;
  height: 100px;
  background-color: blue;
}
