The most common and simplest way to set a rounded border in css is to use the border-radius attribute.

CSS rounded corners only need to set one property: border-radius (meaning "border radius"). You provide a value for this property to set the radii of all four corners at the same time. All legal CSS measurements can be used: em, ex, pt, px, percentage, etc.

<!DOCTYPE html>
<html>
<head>
<style> 
div
{
text-align:center;
border:2px solid #a1a1a1;
padding:80px 40px; 
background:pink;
width:150px;
border-radius:25px;
-moz-border-radius:25px; /* 老的 Firefox */
}
</style>
</head>
<body>
<div>圆角边框</div>
</body>
</html>

border-radius can also use slashes to set the second set of values. The first set of values represents the horizontal radius, and the second set of values represents the vertical radius. The second set of values can also set 1 to 4 values at the same time, and the application rules are the same as the first set of values.

In addition to setting four rounded corners at the same time, you can also set each corner individually. Corresponding to the four corners, CSS3 provides four separate properties:

border-top-left-radius

border-top-right-radius
border-bottom-right-radius
border -bottom-left-radius

These four properties can be set to 1 to 2 values at the same time. If you set a value of 1, it means that the horizontal radius is equal to the vertical radius. If 2 values are set, the first value represents the horizontal radius and the second value represents the vertical radius.
