CSS3 Border Radius

 

CSS3 Border Radius Explained

CSS3 border-radius takes one parameter, which is the width of the curve from the central point. If all the corners are to have the same border radius, then only one parameter needs to be specified.

css
#box {
border-radius: 5px;
}

If any of the corners are different you need to specify each one separately

css
#box{
border-top-left-radius: 5px;
border-top-right-radius: 10px;
border-bottom-right-radius: 20px;
border-bottom-left-radius: 15px;
}
