I've done some mathematics to find the series of a certain element in the background of my current website. I've narrowed down the precise location to:
bottom: calc((737px - ((100vw / 200px) * 64px)) + 70px)
But in Chrome, the developer tool has crossed it out as unrenderable.
I'm wondering what point in this calculation has failed?
You seem to expect the browser to figure out how much 200px (respectively 64px) is, as a ratio, from current browser width and automatically use that value.
Current browser implementation of calc only allows multiplication and division with numbers:
... : calc(100vw / 3) // valid
... : calc(1200px / 3) // valid
... : calc(1200vw / 200px) // NOT valid
See calc() current definition.
