CSS border-start-start-radius

The border-start-start-radius property in CSS is used to set the radius of the top left corner of an element's border. This property is generally used in combination with the border-start, border-end, border-top, and border-bottom properties to create rounded corners for elements.

The syntax for the border-start-start-radius property is:


selector {
  border-start-start-radius: value;
}

Where selector is the CSS selector for the element you want to target, and value is the radius value for the top left corner of the element's border.

Result:

This is an example of using the border-start-start-radius property to create a rounded corner.

In the example above, we have a div element with a border that has a radius of 10px set for the top left corner using the border-start-start-radius property. This creates a rounded corner effect for the element.
