Have a small problem with the plus/minus buttons on my Pomodoro Clock. For some reason, after you click on either one and release the mouse button, there is a very faint light blue border around the button…or maybe the span on top of it.

I’ve looked through my CSS, but I can’t find out what might be causing it. I tried copying the functionality from my Calculator app, and I’ve confirmed that the buttons on that app with similar functionality are not doing this, or at least not that I can see. Any help on this would be appreciated.
