I am using OJS 3.0.2. We have been using since 2018. I am trying to reduce to gap/margin between to section (Article and Book Reviews, Editorial ). Can any one help me. How can I customize? Which file, I need to customize.
Can you describe in more detail what you want to do? Do you mean you’re trying to change the visual appearance of sections in your issues? If so, can you send a link to an example issue where you would like to reduce the gap?
(3.0.2 is very old and no longer supported, so it will no longer receive security updates. I strongly encourage you to update to 3.2+.)
