CSS border-radius Property
The CSS border-radius property defines the radius of an
element's corners.
Tip: This
property allows you to add rounded corners to elements!
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.
CSS border-radius - Specify Each Corner
The border-radius property can have from one to four values.
Here are the rules:
Four
values - border-radius: 15px 50px 30px 5px; (first value applies
to top-left corner, second value applies to top-right corner, third value
applies to bottom-right corner, and fourth value applies to bottom-left
corner):
Three
values - border-radius: 15px 50px 30px; (first value applies
to top-left corner, second value applies to top-right and bottom-left corners,
and third value applies to bottom-right corner):
Two
values - border-radius: 15px 50px; (first value applies
to top-left and bottom-right corners, and the second value applies to top-right
and bottom-left corners):
One value
- border-radius: 15px; (the value applies to all four corners,
which are rounded equally:
Here is the code:
Example
#rcorners1 {
border-radius: 15px 50px 30px 5px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners2 {
border-radius: 15px 50px 30px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners3 {
border-radius: 15px 50px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners4 {
border-radius: 15px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
You could also create
elliptical corners:
Example
#rcorners1 {
border-radius: 50px / 15px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners2 {
border-radius: 15px / 50px;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
#rcorners3 {
border-radius: 50%;
background: #73AD21;
padding: 20px;
width: 200px;
height: 150px;
}
