Hi Sybre!
Thank you so much for your help! I’m hopeful that there will be some improvements soon.
In my personal opinion, I prefer using HTML more and limiting CSS to the minimum. I believe that using the method from the Breadcrumb NavXT plugin would be easier and more effective. For the margin, we can use: “ (space)” instead of adding margin. For example: “?” would be “ » ” (space ? space). I hope it will be helpful for you!
Have a wonderful day!
