If you are looking into adding rounded corners to HTML elements, you can use the following CSS properties.
Following code works with Firefox, Chrome
-moz-border-radius: 20px;
-webkit-border-radius: 20px;
For IE9 use the following code
border-radius: 20px;
If you want to have only one rounded corner on the HTML, I found the following nice website which allows you to change rounded corners as you wish. Full credit to the website’s owner / developer
