[182] New WebKit Features in Safari 11.1 | WebKit
()
https://webkit.org/blog/8216/new-webkit-features-in-safari-11-1/
Animated image formats are very popular, but they easily become large, bandwidth intensive file sizes. To address the performance impact, WebKit in Safari now supports loading H.264 encoded MP4 video with an HTML <img> tag. This allows content authors to replace animated GIF files that are much larger than H.264 video files and require more processing power to display. Beyond the performance gains, this change also allows web content authors to use videos as a CSS background-image.

15年くらい前の記事がなぜ上がってきた?と思ったら昨日の記事でびっくりw
仕様レベルでは10年前にとっくに解決済みなのに、
未だに img 要素を p 要素に入れるべきか否かみたいなことを言ってる人がいるとは。
タイムスリップしたみたいな懐かしい感覚だwww
この記事、
「今日は何年何月何日ですか? この記事は、古い情報について書かれている可能性があります。」
と煽っているわりに
HTML 5.3
とかいう W3C にすら見捨てられた怪文書を参照しているし、
HTML Standard

HTML 5.2
から引用するとかいう意味不明な感じで、
仕様書から引用して正しいことを言っている風に怪しいこと書いてるのが逆にやばい。
