Explanation:

This HTML document demonstrates how to create a rounded border effect for an element using CSS.
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 create rounded corners for the div. A value of 25 pixels is specified, resulting in a noticeable curvature at each corner.
As a result, the div appears with rounded corners and a solid red border, providing a visually appealing design.
