For some reason when I was adjusting my nav bar, the toggle menu has now dropped out of line of the other nav bar elements. I cannot work out why so would appreciate any feedback re this?
Reason of the problem not in adjusting but in using link-blocks inside the nav-menu. I would recommend to use nav-links instead of link-blocks. Then there will be correct structure in the navbar and will be no issues.
One more tip, do not use different classes for every single nav-link, it will make your work much harder when you will style current state for link and it is not good practice in general.
