I want *one* portfolio simple grid page to have 2 columns instead of 3. Help!

When I try to change one page, they all change. I want the rest of the galleries to stay at three columns but the "SHORTS" gallery to be two. What code should I use?

Here's the page:  https://www.dylankahn.work/shorts

TIA! 

That did it! I LOVE YOU! ❤️

I tried to get that code to work for this page and had luck? Any solutions?

Did you adjust it for your website? You need to use the correct section ID:

@media only screen and (min-width:768px) {
  section[data-section-id="66c6c1c317302605b7a36126"] {
    .portfolio-grid-overlay {
      grid-template-columns: 1fr 1fr !important;
    }
  }
}
