説明

ブラウザの情報は navigator オブジェクトを使います。
navigator オブジェクトには、以下のようなプロパティが用意されています。

navigator.appName (ブラウザ)

navigator.userAgent (ユーザエージェント)

navigator.appVersion (バージョン)

navigator.appCodeName (コードネーム)

navigator.platform (プラットフォーム)

これらを使って、それぞれのブラウザやバージョン、ＯＳを把握して、対応したホームページを表示してあげます。
これ以外にもプロパティやメソッドが用意されていますが、ブラウザに互換がありません。
