CSS border-bottom-left-radius property

The CSS border-bottom-left-radius property is used to set the radius of the bottom-left corner of an element's border. This property allows you to create rounded corners specifically for the bottom-left corner while keeping other corners sharp or applying different radii.

Syntax

selector {
    border-bottom-left-radius: value;
}

Possible Values

Value Description
length Defines the radius in px, em, rem, etc.
% Defines the radius as a percentage of the element's dimensions
initial Sets the property to its default value (0)
inherit Inherits the value from the parent element

Example: Setting Bottom-Left Corner Radius

The following example demonstrates how to apply a specific radius to only the bottom-left corner −

<!DOCTYPE html>
<html>
<head>
<style>
    .box {
        width: 200px;
        height: 150px;
        background-color: #4CAF50;
        border: 3px solid #2E7D32;
        padding: 20px;
        color: white;
        display: flex;
        align-items: center;
        justify-content: center;
        margin: 20px;
    }
    
    .bottom-left-only {
        border-bottom-left-radius: 30px;
    }
    
    .combined-radius {
        border-radius: 10px;
        border-bottom-left-radius: 45px;
    }
</style>
</head>
<body>
    <div class="box bottom-left-only">
        Bottom-left radius only
    </div>
    
    <div class="box combined-radius">
        Combined with border-radius
    </div>
</body>
</html>
Two green boxes appear:
1. First box has only the bottom-left corner rounded with 30px radius
2. Second box has all corners rounded to 10px, but the bottom-left corner is overridden to 45px

Conclusion

The border-bottom-left-radius property provides precise control over individual corner rounding. It can be used alone or combined with other border-radius properties to create unique corner effects.
