CSS3 web fonts

With CSS3 web fonts, web developers can now choose from a limitless selection of

fonts to create stunning new websites using standards-based technology. Safari

automatically recognizes websites that use custom fonts and downloads them as

they’re needed.

CSS animation

Safari is the first browser to support CSS animation. Now anyone can add amazing

interactive animations to their website using open standards. With CSS animations,

web developers can scale, rotate, fade, and skew web elements for elegant, highproduction-

value pages.

HTML 5 media support

The new HTML 5 media tags make it easy for web developers to deliver rich, interactive

video and audio as a native part of any website without the need for proprietary

technologies. The media tags also offer a rich scripting API for controlling media

playback.

Improved SVG support

Safari 3.1 features improved support for Scalable Vector Graphics (SVG), so now

developers can use SVG images anywhere on a page including HTML and CSS

elements. SVG allows developers to create dynamic graphics with the web scripting

languages they’re familiar with.

HTML 5 offline storage support

With offline storage support based on the HTML 5 standard, web developers can

create faster web-based applications that store their information on a user’s local

machine, and then access it instantly rather than having to re-download it over

the Internet.
