Reducing the section size of a Portfolio Page in 7.1

Site URL: https://www.saragisabella.com/work

Hey everyone!

I'm trying to reduce the section height of a portfolio page (hover: follow cursor), but I can't seem to make it work. This piece of code adjusts the section height in the editor preview, but somehow it doesn't work on the live site:

.portfolio-hover-display {
    min-height: 50vh !important;
}

I appreciate your help!
