Aligning logos in navigation menu

I have spent the past few hours researching into how to align the logos I have inserted into my navigation menu and none of the coding I have found have helped me. I’ve never had this much of issue with coding before and I can’t understand what the issue is.

I have inserted the logos by putting the image html into the label of the custom pages I have added to the menu. I want to keep the rest of my navigation on the left hand side, I just want the logos aligned to the right.

Thanks.
