Portfolio Images Mobile Overlay

I figured out how to turn off the hover effect in my portfolio grid using the below code, but now it's hard to read on the mobile. Can someone help me with code to put a overlay gradient on mobile only or a suggestion to make the text legible? Thanks!

// Portfolio Text on Mobile //
@media screen and (max-width:640px) {
.portfolio-text {
    opacity: 1 !important;
  
}
}

@media screen and (max-width:767px) {
.portfolio-text h3 {
    color: white !important;
    font-size: 26px ! important;
}
}

@tuanphan it's the results page: https://metgal.art/results 

Our domain is connected, but the password is still: thisisart
Also, I had to actually go on my phone to see how this portion of the website would look, rather than use Squarespace's built-in feature. 

Add to Home > Design > Custom CSS

@media screen and (max-width:767px) {
.portfolio-overlay {
    background-color: rgba(0,0,0,0.2) !important;
    opacity: 1 !important;
}
}

Thank you!
