I was hoping someone could help me out with an issue.
I am trying to create a node that does not have any other css loaded to it besides what I add to the body of the node. Is there a way to disable the current theme that the rest of the website is using just on one node? I was able to disable all modules and blocks from this blank node and feel as though there is merely a setting I am over looking. Can someone please assist me here.
