I achieved that with the property ColorAreaSize

Good morning, Im creating a user interface template and trying to resize the control box to fit monitor resolution 1366x768 or 1920x1080, so I'm writing the position of the color boxes and controls, but i can't write in the bounds property of the color boxes, is there any other way I can do it? Thanks in advance, and sorry for the english
