  22. 22. Shawnee County&apos;s logo is protected by law.

  23. 23. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks:Get out of Line: Use the DOM<br />It extends easily<br />Classes, ID’s and the DOM make good hooks for JS and style<br />At best, they require a script tag<br />More often they will also need more classes, ids and/or elements.<br />It fails well<br />Users don’t miss it when it’s gone(Everything still works)<br />
  24. 24. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks:JavaScript and Accessibility<br />Some users and UAs don’t see JavaScript fire:<br />Screen readers<br />Audibly indicating DOM-scripting and Ajax changes through screen readers is a booger.<br />Some UAs neglect it; others handle it poorly.<br />Those behind corporate firewalls<br />Some mobile UAs<br />Others with JS disabled (purposefully or not)<br />
  25. 25. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />SemanticsCost and Value<br />Building sloppy code is cheap<br />Maintaining it isn’t: I know.<br />Inline style (and event handlers) create larger files, and make clean-up tedious<br />Semantics offer ad hoc documentation<br />
  26. 26. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />SemanticsWhy Not?<br />Learning curve?<br />Yes.<br />Code Bloat?<br />No…Consider another simple example.<br />
  27. 27. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />SemanticsWhy Not?<br />HTML3 and earlier<br />&lt;table style=&quot;color:#555;background-color:#eee;border:1px #333;vertical-align:bottom; &quot;…&gt;…&lt;tr&gt;&lt;td style=&quot;text-align:right;font-family:consolas,&apos;andalemono&apos;,mono;&quot;&gt;785.555.1212&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;<br />
  28. 28. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />SemanticsWhy Not?<br />HTML4, HTML5, XTHML<br />&lt;table class=&quot;phone-chart&quot;…&gt;…&lt;tr&gt;&lt;td class=&quot;phone-work-fax&quot;&gt;785.555.1212&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;<br />
  29. 29. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks<br />Some practical implementation examples and ideas.<br />
  30. 30. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks:Don’t use XHTML<br />The popular XHTML implementation is incomplete/incorrect.<br />It’s incorrect to send it as &quot;text/html&quot;,<br />It should be &quot;application/xhtml+xml&quot;<br />It’s treated by most browsers as tag soup<br />Have you ever seen xhtml fail like an XML feed would?<br />IE6-8 downloads well-formed XHTML like a binary<br />Consider Ian Hickson’s warning, against the improper implementation of XHTML.<br />
  31. 31. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks:Character Encoding<br />Right after the head, even before &lt;title&gt;:<br />make sure the title and all after are properly encoded<br />It’s important for good data and security…<br />For display<br />You don’t want to see that.<br />For good capture and security:<br />especially with intérñatiönal users<br />
  32. 32. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks:Character Encoding<br />Unless you have particular needs use UTF-8<br />&lt;!DOCTYPE HTML…&gt;&lt;html lang=&quot;en-US&quot;&gt;&lt;head&gt;&lt;meta http-equiv=&quot;Content-Type&quot; content=&quot;text/html; charset=utf-8&quot;&gt;&lt;title&gt;Hello, World&lt;/title&gt;<br />
  33. 33. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks:JavaScript Bottlenecks<br />HTTP/1.1 allows multiple persistent connections.<br />Modern browsers load multiple resources (text, image, audio, etc.) at once:<br />Without manipulation, UAs don’t allow over two scripts to pull in at once.<br />When able, load scripts last (i.e. before &lt;/body&gt;), or use the onload event handler (or similar device) to build your script request dynamically at full load.<br />
  34. 34. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks:CSS Bottlenecks<br />Make CSS external (usu. automatic in VS)<br />But if not, avoid using the @import command in &lt;style&gt; tags, as it causes problems with concurrent downloading in some browsers<br />Place it as soon after the title as possible:<br />&lt;!doctype…&gt;…&lt;title&gt;I am a title&lt;/title&gt;&lt;link rel=&quot;stylesheet&quot;/&gt;<br />
  35. 35. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks:More JS Considerations<br />Be aware of VS controls that generate non-standard mark-up:<br />e.g. ListBox, DropDownList, AdRotator and more.<br />As our DBA always reminds us, never trust the client (device).<br />
  36. 36. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Brass Tacks:More JS Considerations<br />The JS pseudo-protocol is not a protocol…<br />If you use it or inline event handlers with href=&quot;#&quot;, the event will not fire in some cases, leaving users bewildered.<br />
  37. 37. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Conclusion:ROI<br />Ease of extension<br />Value of data: contentis more informed<br />Natural/Accidental/Organic SEO<br />Faster page loads/decreased server load<br />Greater user access/cullability<br />
  38. 38. Shawnee County&apos;s logo is protected by law. All other presentation content is in the public domain.<br />Conclusion:Last Things<br />I won’t be there to blame when your app fails<br />And, they’ll laugh at you for listening to a designer<br />Standards are usually optimal: but not always<br />Standards change: so don’t follow blindly<br />If they don’t help now, they may help later<br />Make your boss happy: the food will follow<br />
