Bug in alignment and small devices

I am using this plugin with customizr theme.
Additionally a sidebar with widgets is used.
I have detected an error on small devices:

When the width of the page is small enough it’s not possible to click
on the navigation buttons. Without your plugin it’s possible.

I have fixed it with this:
.wp-pagenavi{<?php if($options[‘align’]==’right’){echo ‘text-align: right; ‘;} elseif($options[‘align’]==’left’){echo ‘text-align: left; ‘;} else { echo ‘text-align: center; margin-left:auto !important; margin-right:auto; !important’;} ?>}
