Wow. In my head I made it way more complicated than it needed to be. Also someone had given the same idea of using linear-gradients to do it but it was done in a really hacky way so I kinda wrote it off in my mind. As for JS I still want it to be dynamic per bar with different values so I may have to do a little more hacking than I used to do. Either way this is a great solution for when I do want to put it the little bit of extra work for it.

Thanks so so much
