The issue is with bullets in my html file.
I have already tried going to nav ul, the location I need to remove the bullet list and tried including list styles to remove them. Although this works, the formatting of my menu falls apart and I don't know either the cause or the fix for this. So instead I decided to leave the bullets in in the hopes that someone could find a solution for my issue. I've included the css and html code I'm working with. This is my first post so if there's anything I could do better when posting a question, please let me know.
