How can I make a box in my ArcGIS Pro layout transparent?

Question

I've added a rectangle/box to my ArcGIS Pro (v1.4) Layout.  I'd like it to be partially transparent.  Is this possible?

thanks in advance...

Sure. In Pro, any color can be made to be transparent.  For your rectangle in layout. Select it, go to the symbol properties.  Select the color picker and at the bottom of the color pallet select Color Properties... Then set the Transparency to any percentage you'd like.
