CSS border-bottom-left-radius Property
The border-bottom-left-radius property specifies the rounding of the bottom-left corner of the element.
The border-bottom-left-radius property is one of the CSS3 properties.
If you do not specify a value, the corner remains square. When a value is provided, it creates a quarter ellipse. If you use a background image or color, it will be clipped at the border. The process of clipping is defined by the value of the background-clip property.
The border-bottom-left-radius property has two values: length and percentage. When only one value is given, it specifies both horizontal and vertical radii of the ellipse. If two values are given, the first value sets the horizontal radius and the second value sets the vertical radius.
Percentages for the horizontal radius refer to the width of the box, percentages for the vertical radius refer to the height of the box. Negative values are not allowed.
If the border-radius shorthand property is applied after border-bottom-left-radius, it overrides the individual property value.
