Rails3 で twtter bootstrap と will_paginate を使うと表示が崩れる件

（環境: MacOSX10.7, ruby19.2, rails3.1.3, bootstrap-sass-rails1.4.0.3）

こんな感じにズレる

修正してみる

インストール

Gemfile（なんとなくbootstrap-sass-rails使ってみた）

gem 'bootstrap-sass-rails'

gem 'will_paginate', '~> 3.0'

gem 'i18n_generators'

rails g i18n ja

code

config/locales/translation_ja.yml

ja:
  will_paginate:
    next_label: Next →
    page_entries_info:
      multi_page: Displaying %{model} %{from} - %{to} of %{count} in total
      multi_page_html: Displaying %{model} <b>%{from} - %{to}</b> of <b>%{count}</b>
        in total
      single_page:
        one: Displaying 1 %{model}
        other: Displaying all %{count} %{model}
        zero: No %{model} found
      single_page_html:
        one: Displaying <b>1</b> %{model}
        other: Displaying <b>all %{count}</b> %{model}
        zero: No %{model} found
    page_gap: ! '…'
    previous_label: ! '← Prev'
