WP Paginate responsive, drop page numbers under each other?

I am using the WP Paginate Plugin: http://wordpress.org/support/plugin/wp-paginate

When i resize or test on a phone/tablet, the container doesn’t resize even though the width is 100%. Its defiantly the wp.paginate as when displayed as none the rest of my website doesn’t break. Is there a css issue around or a way to get the page numbers to go underneath each other?

Thanks!
