Beee on "[Plugin: WP-PageNavi] Issues with mobile design"

I ran into something I'm not sure is a bug or too few css knowledge on my side :)

On http://www.freerides.org I use the plugin on the frontpage.
When watching the site on a screen which is max 480 pixels wide, the pagination 'breaks'.

I made a screenshot of how the site looks on a 480 and 320 screen.
