How to make elements adapt to the vh in combination with Sticky Nav

Hi,

Im making a site where the hero section is of full viewport height (vw). I am using a sticky nav at the top of my page. Normally I would go and use calc() to calculate the remaining height of the hero (100vh - nav height) so that the hero section doesnt flow over the fold. Is there any native Webflow way to obtain this, or do I just use some custom code?

Thanks in advance!
