Safari supports the latest edition of the JavaScript standard, ECMA 262 version 5.1. With CSS filters, developers can create advanced filter and pixel effects such as blurs and gradients and vary brightness, adjust hues, invert colors, or convert elements to sepia or grayscale. The Web Audio API lets developers create and customize audio effects in interactive web applications with rich media content. And Safari supports HTML5 media synchronization for web pages that require precise timing integration between multiple media elements and text — such as captions, subtitles, descriptions, and chapters. With website notifications, developers can keep users up to date about their sites. |
