twitter bootstrap is a toolkit from Twitter designed to kickstart development of webapps and sites, including styles for pagination. If you're using kaminari as your pagination library, the markup in its default views won't match the selectors used by bootstrap. This repository contains modified copies of kaminari's views that you can drop in to your ruby application to work with bootstrap.
Copy app/views/kaminari into your local Rails app/views folder
These views were tested with kaminari 0.12.4 and bootstrap 1.1.0 and 1.3.0.
Prefer to use HAML over ERB? Lucky for you, Nick Gorbikoff has created a HAML fork for your pleasure.
