How Apple Browser and Devices Support HTML5 & CSS3

Every new Apple mobile device and every new Mac — along with the latest version of Apple’s Safari web browser — supports web standards including HTML5, CSS3, and JavaScript. These web standards are open, reliable, highly secure, and efficient. They allow web designers and developers to create advanced graphics, typography, animations, and transitions.

Apple has demonstrated how the latest version of Apple’s Safari web browser, new Macs, and new Apple mobile devices all support the capabilities of HTML5, CSS3, and JavaScript. Not all browsers offer this support. But soon other modern browsers will take advantage of these same web standards — and the amazing things they enable web designers to do. You can also visit Safari Dev Center for more information about HTML5 and to see how you can add effects like these to your website.
