Max font size when using VW

For the hero section heading, I am using 1vw font size for the wrapper div (heading-hero-wrapper) and 4.75em font size for the text div (heading-hero) so it scales with the screen size, but when the viewer’s screen is very large the text starts to get too big. I added the embedded code below so that the font size to stop at 80px, which works great in preview, but when I publish the site the entire hero section is blank. Is someone able to help me debug this?

<style>
.heading-hero{
font-size: min(4.75em, 80px) 
} 
‹/style›
