Makeing adjustments at each pixel dimension, not just at the exact breakpoints

Hello!

When you are making responsive websites by hand-coding, you can just put the @media and make your changes from there. However, I can’t seem to make little changes in webflow. Like if I wanted to adjust 100vh to 50vh I could not do that at 1920px width and then make it 50vh at 1000px width. I would have to make that change at the tablet breakpoint. Am I missing something? Is there a work for this?
