How about using a Custom CSS option in ElkArte ? Would be really helpful to make changes without doing core file edits.
There already is a way to use custom CSS files for the preferred theme:

I was thinking more like as in WordPress, within the control panel.
Thanks
@Jorin , so I just need to create a .css file with prefix custom_ to modify any ( or just default ) theme ?
Yep, it has to be named custom_nameoftheme.css.
