[SOLVED] 3 points before some elements in panel

[Gerapa]

Hi all,
I've just installed Mint Mate 19.2. In the panel where there are the menu button, list of windows, clock, ... , there are 3 vertical points before some elements. I cannot find how i could hide those 3 points. Have you an idea ?
Thanks in advance.

I beleieve you can right click on them and select properties. Change to invisible or something like that. It's the separator.

Read the solution in this post:

Go down to the section Update for Mint 19.2 under Panel item border appearance

@MrEen : I didn't have a way to change something by right clicking, but thank you for your answer.

@roblm : That did the trick, thank you very much. I created gtk.css and pasted the lines from Pete's answer, and the dots have disappeared. I mark the subject as solved.

Thank you both again.

Ahh, it's Xfce only for what I wrote. Thankfully roblm had the fix, and a great tutorial!
