19. CSS3

• New CSS Selectors to allow for specific targeting for styles
• Delivers a wide range of stylization and effects, enhancing web pages without
sacrificing their semantic structure or performance
• Latest version of the CSS standard, introducing exciting new effects like dynamic
color gradients, 2D and 3D transforms, multi-column and flexible
layouts, calculations, transitions, animations, and media queries to tailor
different styles for different devices
• Not technically part of HTML5, CSS3 is a separate — though closely connected
— set of standards, emerging and evolving in tandem with HTML5
21. Multimedia

• New audio and video elements embed sound and moving pictures into web
pages without any proprietary plug-ins
22. Graphics and 3D

• Make apps more seamless and make dynamic content load faster with a variety of
techniques and technologies such as Web Workers, XMLHttpRequest Level 2 (the
technology behind Ajax), and the History API.

and persistent app databases, like email
