Viewport Width Border Radius

Is there a way to get border radius in something other than pixels? Viewport width for example.

Hey @jimlowrey thanks for the feedback which I will forward to the team. The only thing I will mention that if the radius would be based on the viewport width, the button become more round as the screen gets wider.

Right. The effect I’m looking for is a responsive image with 50% border radius on top left and right. So percent would have been a better request but the image width is based on vw so either would work.
