How do you exclude a specific page from your Custom CSS rules

I have a custom background on all of my pages that I was able to generate using custom CSS, but I would like not to have that background on one of the pages on my website.  

Here is the code:

#page{
background-image:url(https://static1.squarespace.com/static/5e8153bfb44957431114ef44/t/649ca8eb65c764054e3a0785/1687988460154/Blue+Background.jpg);
background-size: cover}
.section-border{opacity:0!important}

Here is the collection ID for the page I want to exclude:

#collection-5e815582abb56b3bf61d9204

Any help would be greatly appreciated, thanks.

Perfect!  Thanks!
