You don't need to add anything to get this CSS to work. It is the default CSS and should work as long as you don't have anything overriding it. That being said, you do have CSS that is overriding it. Specifically, Just remove the line specifying the font family. Note that your font size is currently overridden by the default CSS (so it is still 14px).
