Curriculum Help

Tell us what’s happening:

Can somebody explain why FCC have used an exceeding percentage value of 190% when defining the horizontal border-radius for the .cat-mouth instead of 57px?

Code:
border-radius:190%/190px 150px 0 0 ;

if you use percentages you don’t need to calculate it yourself, and the value stay relative to the width or height of the element box, even if the element changes size
