The "Next Project" button doesn't scale down?

Site URL: http://itsbartek.com

Hey, 

Basically on the web version my "next project" buttons are looking like on the screenshot #1 and then if you go on the phone version it looks like on the screenshot #2.

Is there any way to make it smaller but only on the phone version? If I change the size it changes globally. Is there any way to kind of disconnect them or force it to adjust? 

Thank you!
