Line spacing of checkboxes as custom field

Hello,
I have created a custom field "Present at:" that has two checkboxes "Site_1" and "Site_2" as values.
Would it be possible to reduce the line spacing between the checkboxes? (see attached file)
This would be very helpful, especially with a large number of such checkboxes.

Sincerely
Léon

Your site CSS must be doing something funny.
On my site, the spacing is controlled by my template's CSS for li
... but it might be different for your site (could be margin or padding on li elements, or something else entirely). It would be great to see the code live so it can be diagnosed -- is your site online, and can you post a link?

Here's a screenshot my my site to show that the wide spacing is not the norm for EB

Hello,
thank you for your suggestions.
The file /media/com_eventbooking/assets/css/custom.css at my site is empty.
Unfortunately, my test site is not public.
Some tests with the template's CSS files did not yet show any improvement.
So, I have to wait for someone else to come up with another helpful proposal.

Thank you,
Léon

Hi Léon

You can submit a support ticket sending us super admin account of your site and the link to the page. I will have my template developer check and solve it directly on your site for you
