Explanation:

  • This HTML document demonstrates how to define the shape of corners using the border-radius property in CSS with a percentage value.
  • The div element is styled with a solid border that has a thickness of 3 pixels and a color of #FF0000 (red).
  • Padding is set to 10 pixels at the top and bottom and 40 pixels on the left and right sides of the div.
  • The background color of the div is set to #00CCCC (light blue).
  • The width of the div is set to 150 pixels.
  • The border-radius property is used to define the shape of the corners as a percentage of the div's width and height. In this case, it is set to 20%, which means the corners will be rounded, with the radius being 20% of the width and height of the div.
  • As a result, the div appears with rounded corners, creating a visually appealing design with rounded edges.
