CSS3 border-radius Property
Using the CSS3 border-radius
property, you can create "rounded corners" for any element.
Here are three examples:
- Rounded corners with a background color:
Rounded!
- Rounded corners with a border:
Rounded!
- Rounded corners with a background image:

The code is as follows:
Example
#rcorners1 {
border-radius: 25px;
background: #8AC007;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners2 {
border-radius: 25px;
border: 2px solid #8AC007;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners3 {
border-radius: 25px;
background: url(paper.gif);
background-position: left top;
background-repeat: repeat;
padding: 20px;
width: 200px;
height: 150px;
}
CSS3 border-radius - Specifying Each Corner
If you specify only one value for the border-radius
property, it will apply to all four corners.
However, if you want to specify each corner individually, you can use the following rules:
Four values: The first value is for the top-left corner, the second value is for the top-right corner, the third value is for the bottom-right corner, and the fourth value is for the bottom-left corner.
Three values: The first value is for the top-left corner, the second value is for the top-right and bottom-left corners, and the third value is for the bottom-right corner.
Two values: The first value is for the top-left and bottom-right corners, and the second value is for the top-right and bottom-left corners.
One value: All four corners have the same value.
Here are three examples:
- Four values -
border-radius: 15px 50px 30px 5px
:
Rounded!
- Three values -
border-radius: 15px 50px 30px
:
Rounded!
- Two values -
border-radius: 15px 50px
:
Rounded!
The source code is as follows:
Example
#rcorners4 {
border-radius: 15px 50px 30px 5px;
background: #8AC007;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners5 {
border-radius: 15px 50px 30px;
background: #8AC007;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners6 {
border-radius: 15px 50px;
background: #8AC007;
padding: 20px;
width: 200px;
height: 150px;
}
