The style and template files are regenerated every time NodeBB reloads. To change them permanently, you need to either edit the
style.less of the theme you are using, or enter your custom css under the
Appearance=>Custom HTML and CSS tab in the admin panel.
I recommend using the
Custom CSS option for small changes like this, it's easier and doesn't require a reload.
Sadly, I wasn't able to find that option ? Where it should be?
Is this the right file to edit? (I'm using the "persona" theme)
You can mark this as SOLVED !
Edited the custom css worked !!! THANK YOU A LOT !
