  Agenda The drivingprinciples behind Internet Explorer 8 What are web standards and why should you care? Compatibility What about innovation? WebSlices & Activities What should I do now? Questions What are we going to talk about?

  The driving principlesbehind IE8 Interoperability Write web pages once and have them work cross browser Compatibility Don’t break web pages that are already out there Innovation Introduce new features without effecting the first two principles
• 5.
  Web Standards Drivinginteroperability between browsers
• 6.
  The Three Layersof Web Design The bare content of a web page: text, paragraph structure, images, tabular data Defined in W3C standards like HTML 4.01 and XHTML Represented by tags with semantic, contextual meaning Content tags include: <p>, <code> <h1>, <h2>, <h3> <em>, <strong>, <cite>, <abbr> <img>, <a>, <hr> <ul>, <ol>, <dl>, <table> Structural tags include: <div> <span> Markup file should consist of mostly content & structure The Content Layer

  Compatibility Who knowswhat a DOCTYPE switch is? First introduced in IE5 for Mac Worked for a while… Moving forward… version targeting How do we not “break the web”
• 17.
  Compatibility IE8 usesa completely new rendering engine for standards mode, this is used by default for standards mode rendering Old rendering engine (IE7) is available in both quirks and standards mode IE8 includes improvements to the DOM implementation that may break existing sites, e.g. no more document.all Use the X-UA-Compatible http-equiv meta tag to target a rendering/scripting engine mode: IE8, IE7, IE5 (IE7 quirks) This will be supported going forward so that in IE9 you can target the IE8 rendering engine (no more quirks mode!) Version Targeting

  What about Innovation?How does it fit with web standards? Graceful degradation Progressive enhancement Extend functionality Wide adoption brings wide implementation Standardisation!
• 20.
  Innovations in IE8Defines a portion of a page that’s likely to change User can subscribe to that portion Highlighted in the page and toolbar like an RSS feed Added to the favourites bar, highlighted when new content is received Two classes from hAtom microformat and an extra container <div class=&quot; hslice &quot; id=&quot;1&quot; > <p class=&quot; entry-title &quot;>item - $66.00</p> <div class=&quot; entry-content &quot;>high bidder:buyer1 … </div> </div> WebSlices
• 21.
  Innovations in IE8Contextual menu options which quickly access a service from any web page Easiest way to create a “plug-in” that exposes the services of your web site Used for “look up” and “send to” operations Described via an XML file Installed via JavaScript: <button onclick=&quot;javascript:window.external.addService('GetMap.xml')&quot;> Add Map Activity</button> Activities

  Innovations in IE8Vastly improved JavaScript performance Adaptive Zoom DOM: Storage, Cross Document Messaging (XDM) CSS Selectors API ARIA support Consolidated Add-on management Security improvements Loosely-Coupled IE (LCIE) e.g. tabs run out-of-process Address bar improvements Other improvements
• 25.
  Summary Web standardsare important to interoperability Web standards apply to the three layers of web design: Content Presentation Behaviour IE8 is better adhering to web standards, Acid2 Version targeting allows for compatibility Innovation is good when done correctly WebSlices & Activities What have we seen?
• 26.
  What should youdo now? Download IE8 Beta 1 for Developers Check your websites Add version targeting if needed Update your browser detection code User agent sniffing Conditional comments Learn to use CSS 2.1 WebSlices & Activities Be prepared for lacking tooling, put pressure back on the tooling vendors via blogs, etc.
