Move Gallery Caption

I am trying to target the "box, fit, move" to move more central. It was working until i changed the page name and messed it up. Now i cant figure out why it wont work 

Here is the code:

#collection-5db135610bf54838cb3a9106 {
    .Index section #home1 {
        .Index-gallery-item-content {
            vertical-align: top;
            margin-top: 15vh;
            margin-left: 20vw;
              width: 150px;
        }data-collection-
    }
}

pw: hi 

Actually:

#collection-5db135610bf54838cb3a9106 {
    .Index section #home1 {
        .Index-gallery-item-content {
            vertical-align: top;
            margin-top: 15vh;
            margin-left: 20vw;
              width: 150px;
        }
    }
}

#collection-5db135610bf54838cb3a9106  is Page ID

When you change Page Name, Page ID will change (I guess)
