「[CODE[iframe]] [[要素]]よりも結合度の弱い[[フレーム]]」
[[要素]]の導入は繰り返し試みられてきました。

* 概要

[24] 
いくつかの技術や提案があって、少しずつ要求が違うので、似ているようで違うものができてきています。


[21] [[プラットフォーム]] : 
[[HTML]]、
[[HTML]] をベースにした独自[[プラットフォーム]]、
その他の[[プラットフォーム]]

;; [22] [[HTML]] とも [[HTML]] と関連が深い[[XML応用]]とも違う[[プラットフォーム]]については、
[[アプリ内ブラウザー]]を参照。

[23] 提供目的:
[[広告]]埋め込み、
ミニ[[アプリケーション]]の埋め込み、
外部[[Webサイト]]の紹介、
特定ページ表示用[[Webブラウザー]]機能提供、
汎用[[Webブラウザー]]提供、
など

** [CODE[browser]] 要素と [CODE[webview]] 要素 (HTML)


[96] 
[[Mozilla]] は [[B2G]] ([[Firefox OS]]) の[[アプリ]]の埋め込みに
[CODE[<iframe mozbrowser>]]
を使っていましたが、
これを
[DFN[[CODE[browser]]]]
[[要素]]に切り替えることを[TIME[西暦2012(平成24)年][2012]]、計画しました。

[97] 
平成24年3月時点で [[Mozilla]] では [CODE[browser]] [[要素]]とする計画でした。

[98] 
これを聞きつけた [[Google]] は [[Chromeアプリ]]用の [[Webブラウザー]]埋め込み機能
[[Browser Plugin]] 
を
[[Mozilla]] に合わせて
[CODE[browser]] [[要素]]とすることを平成24年6月に決め7月に実装しました。

[99] 
平成24年8月、 [[Google]] は [CODE[browser]] を
[DFN[[CODE[webview]]]]
に改称することを [[Mozilla]] 側に提案しました。
[[Mozilla]] 側も了承しました。


[100] 
[TIME[西暦2013(平成25)年2月][2013-02]]、 
[[Chromeアプリ]]の機能は [CODE[webview]] [[要素]]として世に出ました。

[101] 
[TIME[西暦2014(平成26)年][2014]]や[TIME[西暦2015(平成27)年][2015]]、
[[Mozilla]] 
では
[CODE[webview]] [[要素]]を実装したり、
[CODE[webview]] [[要素]]を [[HTML]] への拡張として提案したりする動きがありましたが、
未完に終わりました。

>FWIW, Chrome Apps is currently going with <browser> for consistency with Gecko. I've talked informally to the Chrome Apps folk and they are fine with <webview>.

>I'm fine with <webviwe> too. I think <browser> is quite confusing too because things in <browser> are actually tabs, and the browser is the frame containing those. <webview> will reduce quite significantly that confusion.
