Hi, I watched your video on the header builder as it’s been awhile since I’ve used it. I’m trying to use the calc (100vh - 100px) to shift the hero image under the nav bar, but I can’t seem to find the right place to plug in this function. Can you point me in the right direction? Cornerstone has gone through several updates since the video was created and I can’t find a Dimensions section for images as shown.
