4. HTML
• Draft Specification of the next iteration of HTML
• HTML 4 (1997) and XHTML 1 (2000)
• Clearer separation of data and layout/style
• Makes what you would already do in HTML easier
• New Content Tags
• <nav>, <section>, <header>, <article>, <aside>, <summary>
• New Media Tags
• <video>, <audio>, <figure>
• New Dynamic drawing <canvas>graphic tag
• A tag that allows programmatic drawing via JavaScript
• Inline metadata to help search engines identify content
• <span itemprop=“agency”>Moxie Interactive</span>
5. CSS3
• Specification currently under active development since 2005
• Improved selectors for determining which content to effect
• (good support across modern browsers)
• Embeddable font support (TTF, OTF)
• Improved text layout with column support
• Rounded corners, Reflections (WebKit)
• Multiple backgrounds, transforms (rotation, scale, etc), animations
(WebKit)
6. JavaScript APIs
• Local data storage
• Application Cache (offline access)
• Multitasking (Worker processes)
• Sockets (real-time server communication: chat, games, etc.)
• Native Drag and Drop events
• GeoLocation
• Lots of active 3rd party libraries (Prototype, jQuery, etc)
7. The Good News!
• Good support on modern mobile devices (iOS, Android)
• Simpler, more intuitive syntax
• Video and Audio without requiring a plugin
• Incremental improvements to previous HTML challenges
• Much needed next step in HTML evolution
• Creative enhancements: Rounded corners, gradients, text layout
• Emergence of more advanced technologies such as O3D (WebGL)
• Easier SEO than plugin technologies
• Promising Mobile JS Frameworks (Sencha, jQTouch)
8. The Bad News
• The HTML5 spec is DRAFT and is in ongoing development
(change)
• Video support is not standardized
• Not currently a single codec that all browsers will support
• Google WebM (VP 8) (open sourced by Google)
• OggTheora (open source)
• h.264/MP4 (potential licensing issues)
• No supported DRM for video or audio
• Currently no support for cue points or alpha (transparent) video
9. The Bad News…Continued
• Limited desktop browser support
• Only the newest and best have reasonable support
• Internet Explorer will not have decent support until IE9
• Challenges getting consistent page display across browsers
• Graceful page degradation is potentially complex
• Currently no designer tools for creating HTML5 animation or
interactivity (all must be implemented by a developer)
• Limited developer debugging tools
10. What HTML5 is NOT
• A magic bullet for all your mobile and desktop-to-mobile woes
• A replacement for technologies such as Flash or Silverlight
• Immersive RLP’s would be much more time consuming
• Certain functionality would not be possible or cost-prohibitive
• While HTML5 quickly fixes some small-scale HTML issues (video,
audio, layout and fonts), it does not instantly solve architectural
needs for large-scale immersive cross-platform applications
11. Summary
Good
HTML5 has new standards and features that are long overdue
Allows display of multimedia content without need of a plugin
Good and rapidly progressing mobile support
Bad
Spotty desktop browser support
Complexity creating consistent experiences across platforms
Technical limitations on what can creatively be done
12. Recommendations
• Still consider separate desktop and mobile experiences
• For HTML-based desktop experiences, consider simplified modular
layout for streamlined restyling on mobile platforms
• Don’t expect what has been traditionally executed in Flash or
Silverlight to be cost-effective or even possible in HTML
• Clearly understand the target USER and their needs before
recommending a technology
• Design for the chosen technology
