Making a single code block full width on 7.0 Pacific template

I am trying to make a single code block be basically the full width on only one single page, but just leaving a little bit of padding on the left and right. I'm on 7.0, with the "Pacific" template.

I've looked at other similar forum posts and tried what they said, but with not much luck. 

The page is:

https://www.childrenschoir.com/givelively-embedded-test

You can try this code, should just affect that page as targeted by the Collection ID:

#collection-63732dd671cd80143848a381 #page {
    max-width: 1800px;
}

Change the max-width property to however wide you want.

Oh my gosh, that totally worked. Thanks so much Ziggy!

No problem!
