Regarding the comment bubble on the left side of my screen, how do I:
1. Add a hover color? (besides the inactive color)
2. Make the border 3px wide?
3. Change shadow to: 0px 3px 10px 1px rgba(0, 0, 0, .2)
4. Add hover shadow: 0px 1px 3px 2px rgba(0, 0, 0, .15)
(#3 & #4 will make the comment bubble match all my other buttons.)
