Hello, I'm creating a template that I'm going to be selling however as I'm testing it when I transfer it the custom css is lost for any #ids.

Is there anyway of transferring a duplicated site over and keeping the same collection IDs, or an alternative way of targeting id's that will transfer accross.
Site is: https://wild-wood.squarespace.com/
An example would be this strip should be flush with the top of the page and I've used CSS to do this https://wild-wood.squarespace.com/links . But in the copied site it's gone back to the middle as below:
