The section below about safe area insets was updated on Oct 31, 2017 to reflect changes in the iOS 11.2 beta. Out of the box, Safari displays your existing websites beautifully on the edge-to-edge display of the new iPhone X. Content is automatically inset within the display’s safe area so it is not obscured by the rounded corners, or the device’s sensor housing. The inset area is filled with the
With the recent addition of SharedArrayBuffer, concurrency is finding its way into the JavaScript language. This addition allows JavaScript programs to perform concurrent access to SharedArrayBuffer objects. WebKit supports SharedArrayBuffer and it has full optimization support in our compiler pipeline. Unfortunately, JavaScript does not allow any objects other than SharedArrayBuffer to be shared.

Jun 5, 2017 by Saam Barati, Yusuke Suzuki & Filip Pizlo @saambarati Update: The previous version of this post showed performance data from ARES-6 version 1.0.

Apple’s WebKit team today proposed a new Community Group at the W3C to discuss the future of 3D graphics on the Web, and to develop a standard API that exposes modern GPU features including low-level graphics and general purpose computation. W3C Community Groups allow all to freely participate, and we invite browser engineers, GPU hardware vendors, software developers and the Web community to join
As of r209827, 64-bit ARM and x86 WebKit ports use a new garbage collector called Riptide. Riptide reduces worst-case pause times by allowing the app to run concurrently to the collector. This can make a big difference for responsiveness since garbage collection can easily take 10 ms or more, even on fast hardware. Riptide improves WebKit’s performance on the JetStream/splay-latency test by 5x, wh

この記事の内容は古びている。この記事が最初に執筆されたのちに、CSS Overflow Module では line-clamp プロパティが定義された。この line-clamp プロパティは max-lines、continue、block-ellipsis プロパティに対する一括指定プロパティである。 結論からいうと、CSS の -webkit-line-clamp プロパティは使わないほうがいい。現状および今後の Web ブラウザでのサポートが望めないからである。 -webkit-line-clamp CSS プロパティとは何か 複数行でも3点リーダーをきかせることができるというもの。 このプロパティはどうやって使うか -webkit-line-clamp プロパティ単体では効果を持たず、他のプロパティと組み合わせて使う。 selector { display: -webkit-b
