it's at the bottom of the bottom panel when you click on "Bibliography" on the left in the CSL editor (assuming you're talking about: http://editor.citationstyles.org/visualEditor/ )
Hi! Thanks for prompt reply - so appreciated. I've figured out your instructions above now. When I download the modified style with the entry spacing variable set to 1, it has not changed anything. Any ideas? I've got a 27-page bibliography so doing this manually sucks. Thanks so much
EDIT: I did not figure out the issue with the CSL editor but using the solution below I solved my problem. Thanks
