user
```ruby
module WillPaginate
  module ViewHelpers
    # This class does the heavy lifting of actually building the pagination
    # links. It is used by +will_paginate+ helper internally.
    class LinkRenderer < LinkRendererBase

    protected
    
      def page_number(page)
        unless page == current_page
          link(page, page, :rel => rel_value(page), :class => "btn")
        else
          tag(:a, page, :class => 'current active btn')
        end
      end
      
      def gap
        text = @template.will_paginate_translate(:page_gap) { '&hellip;' }
        %(<a class="gap btn disabled">#{text}</a>)
      end
