Recently, I've been facing an issue with the "hamburger" button in my navbar. Whenever I click on it, nothing seems to happen. This was not a problem before, and now I can't seem to figure out what went wrong or where the error lies.
If anyone could take a look at it, I would greatly appreciate it.
CSS:(This is unrelated to the navbar, but I'm including it just in case)
@import url('https://fonts.googleapis.com/css?family=Source+Sans+Pro:100,200,300,400,500,600,700|Roboto+Condensed:100,200,300,400,500,600,700');
