Create the following div on your HTML page as below:

< div id=”circularDiv” class=”circluarDiv” >< /div >

Add the following css in your html file or common css file that you’re importing:

.circluarDiv {
     width: 100px;
     height: 100px;
     background-color: whitesmoke;
     border: 1px solid black;
     border-radius: 50%;
 }

Please note that the width and height should be equal for the div. Keep the border and background colours distinct to easily recognize the element.

The border-radius is giving rounded corners to the Div.
