Every time I add a new item to the page, my side nav bar shifts downwards away from the position I want it in, is there any way I can fix this, please? So when I add new items it doesn’t shift down and it stays in the same place.
There are a few things that would help this situation:
Define your navbar first.
Set it’s position to be fixed, as well as being in the top right.
Decide if you want to use grid or flex to ensure the spacing between your navbar and content is well defined. Then set up 2 containers to separate them.
