If you specify only one value in the border-radius property, then Create 4 fillets.
However, if you want to specify the four corners one by one, you can use the following rules:
Four values: The first value is the upper left corner, the second value is the upper right corner , the third value is the lower right corner, and the fourth value is the lower left corner.
Three values: the first value is the upper left corner, the second value is the upper right corner and the lower left corner, the third value is the lower right corner
Two values: the first value is the upper left corner and the lower right corner, the second value is the upper right corner and the lower left corner
One value: The four rounded corners have the same value
