Using Page ID to set background images not working

[TankNicole]

Hello! My site at 054.B12.myftpupload.com has one background image set per customizer settings. As instructed through the forum I am trying to set a few custom background images throughout using the Page ID within CCS customizer, but when I use the snippet as instructed, it only appears as a quick fade out and leaves the site-wide background showing still. Here is what I am using:

.page-id-337 {
background: url(http://054.b12.myftpupload.com/wp-content/uploads/2017/10/2.jpeg);
}

Hoping this would override the primary background but it doesnt, page ID is correct. Thanks for your help!

Hello There,

Thanks for writing in!

You do not need the css code. If you want to override the global customizer page background, you will have to edit the page and find the page background image in the Page Settings.
