2. Browser wars
3. Technology wars
4. Massive multiplayer wars
5. We’re distracted.
6. What makes us love the web?
8. The web has unique strengths
9. Playing to the web’s unique strengths Linkability Searchability Ephemerality Interoperability Openness An interconnected and indexed set of 33 trillion pages that run cross-platform and are publically viewable.
10. Write on the page and share it Search faster with Cortana Save it for later in your Reading List Run the x-browser code with EdgeHTML Plan for the future via our open roadmap Linkability Searchability Ephemerality Interoperability Openness

12. A fork from the past
13. The engine split
15. Interoperability: a new approach
17. “The web should just work for everyone – users, developers, and businesses.”
18. If standard defines an API behavior but all other browsers behave differently, is it a standard? Interoperability means the web “just works” if ($.client.profile().name === 'msie') { var IHateIE = { 'scrollTop': context.$textarea.scrollTop(), 'pos': context.$textarea.textSelection('getCaretPosition', {startAndEnd: true}) }; context.$textarea.data('IHateIE', IHateIE); } For some reason IE seems to be calculating that differently. You might have to put in a special rule for IE there. In Chrome, the error does not occur, the xml is appended successfully and the other methods after these two run as expected. In IE however, a hierarchyRequestError is thrown at the appendChild statement. no matter HOW I passed the ko object to the child window, something got lost. Horrible behavior, IE... Why does the following code throw an 'Unspecified error' (on the appendChild line) in IE11 which I click the button?
19. Getting the right, modern content

26. Please don’t do UA sniffing
27. Please don’t do UA sniffing Please avoid UA sniffing as much as possible Always do feature detection (If isolating a bug) Sniff for specific browser versions Assume unknown browsers are good
28. Interoperable intersection The Mobile Web
29. Interoperable intersection The Mobile Web
30. Prioritizing interop Interop 2 Interop 1 Interop 3 Interop 0 Worked in IE11 Used by real sites Works in other browsers We anticipate sites will require this functionality soon Real site usage is farther out or never
31. Font Resource Handling Before loading font resources, IE and Firefox check the font server’s CORS header, and the font’s installable header (as per W3C specification). This is done to ensure that the font usage rights are honored. WebKit does not check CORS / installable header. before after
32. Control Appearance Overrides Apple added ways to restyle HTML controls on the iPhone to match OS control look and feel. Web developers add custom markup to disable Apple’s styles and provide their own. -webkit-appearance: none ← Most common value. -webkit-appearance: button -webkit-appearance: checkbox -webkit-appearance: radio etc.. before after
33. Control Appearance Overrides Some sites restyle input controls using -webkit-appearance: none for critical functionality. before after
34. Gradients Apple originally added support for gradients to WebKit using a Core Graphics friendly syntax. During standardization the syntax was changed leaving WebKit incompatible with the standard. Some sites continue to use the original Apple syntax. Proprietary Apple Markup (still in WebKit): -webkit-gradient(linear, left top, right bottom, colorstop(0, #FFFFFF), color-stop(1, #00A3EF)); Webkit-prefixed W3C Standard Gradient in WebKit: -webkit-linear-gradient(top left, #FFFFFF 0%, #00A3EF 100%); Unprefixed W3C standard: linear-gradient(to bottom right, FFFFFF 0%, #00A3EF 100%); before after
35. innerHTML orphaned children
36. Interop patterns we’re working on Bugs where we’re just plain wrong Standards we’re missing Unstandardized but interoperable APIs “defacto” differences from standards Bugs in other browsers innerHTML orphaned children Web audio, preserve-3d, RTC, CSP, responsive images -webkit-appearance, <meta viewport> <meta http-equiv="refresh" content="0;http://foo.com" /> body.scrollTop versus documentElement.scrollTop, DOM prototypes
37. To date, we’ve made of these types of fixes in Edge.
38. Removing code (yay!) VML attachEvent() VB Script Conditional Comments X-UA-Compatible currentStyle currentStyle IE Layout Quirks MS-prefixed Events
39. interface AesGcmEncryptResult { readonly ciphertext constructor readonly tag } interface ApplicationCache : EventTarget { function addEventListener function dispatchEvent function removeEventListener } interface Attr : Node { readonly boolean expando } interface AudioTrackList : EventTarget { addEventListener dispatchEvent removeEventListener } interface BookmarkCollection Remembering the IEisms that have passed

43. Implementing XPath: crawler data in action
44. Implementing XPath: crawler data in action
45. Hypothesis: Most XPath queries can be rewritten in CSS selectors //element1/element2/element3 //element[@attribute="value"] .//*[contains(concat(" ", @class, " "), " classname ")] element1 > element2 > element3 element[attribute="value"] *.classname
