The block ID is not working

Site URL: https://www.mjsentertainmentspot.com/bookings

I'm trying to add a drop shadow to my text using this code:
  #block-yui_3_17_2_1_1728861408303_19009{
text-shadow: 3px 5px 3px rgba(0,0,0,.6);
}

I changed the filler text to the block ID using the Squarespace ID finder. I tried many options but the shadow isn't appearing on my text. I may be missing something simple here, but I have no clue. I've been having this issue for a little while.

You have a syntax error in your selector.

.user-items-list-simple .list-item[data-is-card-enabled="true"] #block-yui_3_17_2_1_1728861408303_19009 {
  text-shadow: 3px 5px 3px rgba(0,0,0,.6)
}

The .user-items-list-simple .list-item[data-is-card-enabled="true"] is the issue. After removal.

Let us know how it goes.

Thank you, this worked!
