CSS border radius

The border-radius CSS property rounds the corners of an item's outer border edge. You can set a single radius to make circular corners, or two radii to make elliptical corners.

CSS border radius - how to create - example

With CSS, you can give each element "rounded corners" using proprietary border-radius.

Example 1:

#example-coner1 {
border: 2px solid red;
padding: 10px;
border-radius: 15px;
}

#example-coner2 {
border: 2px solid blue;
padding: 10px;
border-radius: 20px 6px;
}

Note: The four values for each radius corner are given in this order: 1. top-left, 2. top-right, 3. bottom-right, 4. bottom-left. If bottom-left is missing it is the same as top-right.

CSS border-radius - Specify each corner - How to create

If you specify a single border property radius value, this radius will be applied to all four corners.
However, you can specify each corner separately if you want. Here are the rules:

Four values: the first value is valid for the top left, the second value is applied from the top right, the third value is applied to the bottom right, and the fourth value is applied in the lower-left corner
Three values: the first value is valid for the top left, the second value is for the top-right and the lower-left, and the third value is applied to the bottom-right
There are two values: the first value is applied to the top left and right-hand corner, and the second value is applied from the top right and the lower-left corner
A single value: all four corners are rounded evenly
Here are three examples:
1. Four values - border-radius:15px 50px 30px 5px:
2. three values - border-radius:15px 50px 30px:
3. There are two values - border-radius:15px 50px:

Example 2:

.corner-radius4
{
border-radius:15px 50px 30px 5px;
padding:10px;
width:250px;
height:180px;
border: thin solid #0C0;
margin-left: 18px;
margin-top: 10px;
float: left;
}
.corner-radius5
{
border-radius:15px 50px 30px;
padding:10px;
width:250px;
height:180px;
border: thin solid #0C0;
margin-left: 18px;
margin-top: 10px;
float: left;
background-color: #9FF;
}
.corner-radius6
{
border-radius:15px 50px;
padding:10px;
width:250px;
