  1. Developing with Internet Explorer, now and the future Zlatko Knezevic Developer Evangelist Microsoft zlatko.knezevic@microsoft.com

  2. World Wide Web • Came a long way from CERN and Tim’s idea • First, it was content-oriented • Then, it was data oriented • Now, it’s people-oriented

  3. Evolution of the Web The HTML5 Web:Graphically- and Media-Rich The AJAX Web: JavaScript + DOM + Asynchronous Requests Web “2.0” The Content Web: HTML & CSS Web “1.0”

  4. Current browser landscape • Several “big players” that we all know • Internet Explorer, Firefox, Safari, Chrome, Opera • Going to different platforms, we have even more • When we talk about browsers these days, we are talking about engines • Rendering engines (Trident, WebKit, Gecko, etc.) • JsVM (Chakra, V8, Rhino, etc.)

  5. Good thing we have standards, eh?

  6. Internet Explorer 8

  7. Internet Explorer 8 • Better standards compliance & performance • More robust user experience • Developer enhancements • Emerging standards support

  8. Performance • Parallel connection limit increased to six • Pre-parser doesn’t block at script tags • Layout engine faster • Jscript improvements (70% faster than IE7!) • Look ups • Garbage collector • Marshalling • …

  9. Security • Integrated anti-phishing protection • Secure development lifecycle (SDL) IEAK, centralized build and update management • Extended validation (ev) ssl certificates • Domain highlighting • Integrated cross site scripting protection • HTTP only cookies • Legacy versions support (10 years) • Inprivate filtering (control of 3P data sharing) • 24/7 escalation for phishing and malware • P3P support • Anti-spoofing int. Domain names control • Cross document messaging (XDM) • Centralized add-on management • Integrated click-jacking prevention

  10. User experience • Security and speed are one • Add-ons like accelerators and web slices • Better searching with Open Search definitions

  11. Compatibility • Publishers have full control over the layout • “X-UA-COMPATIBLE” META tag or HTTP header IE8 Layout Engines IE7 Compatibility IE6 Quirks IE8 Standards

  12. Developer Productivity • CSS, HTML and Javascript debugger “in the box” • Page “live editing” • Execution control (breakpoints, immediate window, step into, …) • Layout box model, style tracing • Profiler

  13. Looking Forward to the Future • HTML 5 • XDR/XDM • JSON • CSS selectors • DOM storage • Mutable DOM prototypes • Ajax navigation • Network connection awareness • CSS 3 • Box-sizing • Vertical-text

  14. Internet Explorer 8 tricks in practice DEMO

  15. Internet Explorer 9

  16. The main themes • Speed • Interoperability • The future NOW!

  17. In more details… Top Objectives of Internet Explorer 9’s Web Platform • Interoperable HTML5 Markup • Interpret the same HTML and CSS markup the same way • Run the same JavaScript the same way • GPU-powered HTML5 Graphics and Media • HTML5 demands a high-performance graphics subsystem • Across-the-board High Performance HTML5 • JavaScript execution • Page layout • Page display

  18. Markup Languages in IE9 • HTML5 • Defines the behavior at seams of other specs • Parsing unknown elements • Inline SVG • XHTML/XML • Strict, fail-fast parsing helps developers find errors quickly • Easier to process outside the browser • Namespaces for safely using custom elements • SVG • Standalone XML-based document (.svg file) • Inline in an XHTML document • Inline in an HTML5 document

  19. CSS Infrastructure • CSS3 Selectors • Help you do more on your site with less script, simpler markup • CSS3 Namespaces • Style elements with namespaces in XHTML documents

  20. IE9 Programming Model • Central part of web platform used to manipulate the DOM • DOM Core • DOM Events • DOM Style • DOM HTML • DOM Range • HTML5 Selection

  21. Markup and Programming Model in Internet Explorer Platform Preview

  22. DEMO

  23. GPU-powered HTML5 Graphics and Media HTML5’s graphical richness demands a high-performance graphics subsystem • By harnessing the power of the GPU we • Allow features such as alpha-channel blending to be implemented with high performance • Deliver the frame rates needed for smooth animation and video playback • Reduce CPU load from graphics allowing other systems to perform faster

  24. GPU-Powered HTML5

  25. Rich Graphics: A Cornerstone of HTML5 • Graphically-rich styling • Enhanced image support • Scalable vector graphics • Media elements To deliver consistent high quality and high performance, IE9 builds these capabilities on the GPU-powered graphics of Windows 7

  26. Graphically-rich Styling with CSS3 • CSS3 Color • Alpha color with rgba() and hsla() color functions • Transparency control with the opacity property • CSS3 Backgrounds and Borders • Round corners with the border-radius property • Multiple background images per element • box-shadow property on block elements

  27. Enhanced Image Support • ICC version 4 and version 2 color profiles • Images with embedded color profiles are correctly displayed • New JPEG XR format • Higher compression ratios that JPEG • Higher quality with the same file size • Equal quality with smaller file sizes • JPEG XR also supports lossless compression • Valuable for exchanging high-resolution original photography • TIFF image format • Popular for lossless image exchange, black & white images, scanned documents and faxes

  28. Scalable Vector Graphics • Markup-/DOM-based graphics: SVG 1.1 • “View source” simplicity—aids learning • Easy server-side generation—it’s just XML • Easy client-side debugging—it’s in the DOM • Supported by popular graphics programs • Easy integration with HTML5 <svg width="400" height="200" xmlns="http://www.w3.org/2000/svg"> <rect fill="red" x="20" y="20" width="100" height="75" /> <rectfill="blue" x="50" y="50" width="100" height="75" /> </svg>

  29. SVG in Internet Explorer Platform Preview

  30. Rich Media Integration—Without Plugins • HTML5 <video> element • Industry-standard MPEG-4/H.264 video • Video can be composited with anything else on the page • HTML content, images, SVG graphics • GPU-based implementation capable of maintaining 60fps full-screen at full HD resolution • Supports both DXVA and full hardware video decoders • HTML5 <audio> element • Industry-standard MP3 and AAC audio
