Help Plugin My Calendar Please – CSS or Coding help

Hi, I am using My Calendar and it’s a nifty little event calendar. I do have one question and I hope someone can help me with this. The “Previous” and “Next” buttons on the top of the calendar are one on top of the other, and no matter what I do to try to shorten the words, etc, they never move to be side by side. I WANT them side by side.

Is this a font sizing thing, I can’t help but think not since cutting the words down to just a few letters still had them one on top of the other. So I’m wondering if it’s coded in somewhere to be like this, and if there is a way for me to change it?

I’m not the most comp-savvy soul, but I can usually find my way around a CSS to change color and size. But this one has me stumped. Someone please help!
