This style removes ads and widens the message area of Gmail. This style is inspired by the great style "Gmail Cleaner and Tweaker" http://userstyles.org/styles/4211 .

Gmail の広告を非表示にして、メッセージ領域を広告領域まで広げます。「Gmail Cleaner and Tweaker」 http://userstyles.org/styles/4211 というすばらしいスタイルを基にしました。「Gmail Cleaner and Tweaker」はいろいろな機能を持っていますが、そのせいもあってかコードがおかしなことになってしまっていました。なので、機能を2つに絞って適当なコードにした「Gmail Ads-block and Full-width」というスタイルを書いてみました。グーグルさんと広告主の方々には申し訳ありません。
