Hello, in order to change the hero title size in all portfolio items plz add this to customizer -> additional css

@media only screen and (max-width: 1466px){
    .uppercase-text .hero-title {
        font-size: 8vw;
        line-height: 8vw;
   }

}

/* for resolutions greater than 1466px */

.uppercase-text .hero-title {
    font-size: 9vw;
    line-height: 9vw;

}

basically you need to change the values 8vw and 9vw for font size and the line height (set a lower value in view units or pixels)
