CSS3 border-radius Property
With CSS3, you can give any element "rounded corners", by using the border-radius property.
Here are three examples:
1. Rounded corners for an element with a specified background color:
Rounded corners!
2. Rounded corners for an element with a border:
Rounded corners!
3. Rounded corners for an element with a background image:
Rounded corners!
Here is the code:
Example
#rcorners1 {
border-radius: 25px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners2 {
border-radius: 25px;
border: 2px solid #73AD21;
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;

Tip: The border-radius property is actually a shorthand property for the border-top-left-radius, border-top-right-radius, border-bottom-right-radius and border-bottom-left-radius properties.
CSS3 border-radius - Specify Each Corner
If you specify only one value for the border-radius property, this radius will be applied to all 4 corners.
However, you can specify each corner separately if you wish. Here are the rules:
Here are three examples:
1. Four values - border-radius: 15px 50px 30px 5px:
2. Three values - border-radius: 15px 50px 30px:
3. Two values - border-radius: 15px 50px:
Here is the code:
Example
#rcorners4 {
border-radius: 15px 50px 30px 5px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners5 {
border-radius: 15px 50px 30px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners6 {
border-radius: 15px 50px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}

You could also create elliptical corners:
Example
#rcorners7 {
border-radius: 50px/15px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners8 {
border-radius: 15px/50px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners9 {
border-radius: 50%;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
