I'm having difficulty getting the .active class to work on my site. It's hard to show through jsfiddle but here it is. Here's a picture of what I'm looking at. I'm not sure what element in the HTML I should be targetting to make it active since I have all this Liquid in here.
You can see I'm on index.html and it's not making the "Hhome" button black.

This are the different variations that I tried but didn't work. I'm not sure how to make this work with jekyll since it's assigning the class "active" when I serve it...
#navbar ul .active a
#navbar ul.active a
#navbar ul li a
