CMS custom code

Tried asking this before but I think I’ve found a better way to ask so hopefully some kind person out there will be able to help!

Is there a way to have each item in a CMS list be positioned lets say for example 100px from the previous item? Can this be done using custom code, maybe using nth child code?

I’m extremely new to this but I’m hoping to achieve the below but with a CMS list instead.
