4. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Inseparability SEO, semantics, access/accessibility, etc. are like yarn on a sweater: Carefully interwoven Indiscernibly disparate Separating these topics can be difficultDon’t do it: they work together well

Access:Document Object Model Ad hoc API Three simple examples: Web Clips—Safari 3+ Web Slices—IE8 (product site) Requires some add’l coding “FireClips”—FF3 (video|add-on) Other capabilities available and coming
10. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Access:DOM—Extensibility It can be traversed, styled, destroyed, created, and appended to dynamically JavaScript Style: CSS/XSLT Server-side code: PHP and Ruby (on Rails) among others support this In the future in Visual Studio?Don’t be surprised, but don’t hold your breath.
11. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Access:User Interface Offer users early access to the whole page: e.g. “Go directly to content, or navigation.” Hide it from screen and print devices, etc. Offer it to mobile, non-standard devices, etc. JavaScript is not everywhere. Consider your audience.

SEO, Semantics and Standards Standards add previously unrealized functionality Microsoft’s XHR (XML HTTP Request):Now Ajax (or AJAX if you insist) Microsoft’s JPEG XR (HD Photo, previously Windows Media Photo): Better compression for even larger image files, both lossy and lossless
18. Organic SEOHow Standards and SEO Relate Semantic tagging informs content Good: head>title, h1, span.phone-number Poor: font, small, big, b, i, blink Metadata fills in the gaps with keywords, authorship, date and other information Dublin Core metadata is a good framework Shawnee County's logo is protected by law.

20. Shawnee County's logo is protected by law. All other presentation content is in the public domain. SemanticsInforming Data Framework for categorization and the DOM: h1-h6, dl, dt, dd, ol, ul, li, dfn, abbr, p, address Classes (and IDs) further augment good semantics abbr.acronym, ol.contents, span.phone-work-voice, span.name-last, ul.ingredients, ol.instructions, div#content, div#footer-legal
21. Shawnee County's logo is protected by law. All other presentation content is in the public domain. SemanticsInforming Data Semantics help us and machines cull data: Widgets: clips, slices etc. Microformatslike hCard, hCalendar, hAtom and hReview Google now uses RDFa/hReview and hCard You don’t need to pioneer these technologies Google took years to jump on microformats Firefox didn’t get over20% market in a day But folks are using these now All 3 big browsers use Web Slices/Clips
22. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:Get out of Line: Use the DOM Standards make using JavaScript, DOM scripting and Ajax easier and better It eases maintenance Less inline code It keeps code legible… Again, less incline code
23. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:Get out of Line: Use the DOM It extends easily Classes, ID’s and the DOM make good hooks for JS and style At best, they require a script tag More often they will also need more classes, ids and/or elements. It fails well Users don’t miss it when it’s gone(Everything still works)
24. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:JavaScript and Accessibility Some users and UAs don’t see JavaScript fire: Screen readers Audibly indicating DOM-scripting and Ajax changes through screen readers is a booger. Some UAs neglect it; others handle it poorly. Those behind corporate firewalls Some mobile UAs Others with JS disabled (purposefully or not)
25. Shawnee County's logo is protected by law. All other presentation content is in the public domain. SemanticsCost and Value Building sloppy code is cheap Maintaining it isn’t: I know. Inline style (and event handlers) create larger files, and make clean-up tedious Semantics offer ad hoc documentation

29. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks Some practical implementation examples and ideas.
30. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:Don’t use XHTML The popular XHTML implementation is incomplete/incorrect. It’s incorrect to send it as "text/html", It should be "application/xhtml+xml" It’s treated by most browsers as tag soup Have you ever seen xhtml fail like an XML feed would? IE6-8 downloads well-formed XHTML like a binary Consider Ian Hickson’s warning, against the improper implementation of XHTML.
31. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:Character Encoding Right after the head, even before <title>: make sure the title and all after are properly encoded It’s important for good data and security… For display You don’t want to see that. For good capture and security: especially with intérñatiönal users
32. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:Character Encoding Unless you have particular needs use UTF-8 <!DOCTYPE HTML…><html lang="en-US"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>Hello, World</title>
33. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:JavaScript Bottlenecks HTTP/1.1 allows multiple persistent connections. Modern browsers load multiple resources (text, image, audio, etc.) at once: Without manipulation, UAs don’t allow over two scripts to pull in at once. When able, load scripts last (i.e. before </body>), or use the onload event handler (or similar device) to build your script request dynamically at full load.
34. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:CSS Bottlenecks Make CSS external (usu. automatic in VS) But if not, avoid using the @import command in <style> tags, as it causes problems with concurrent downloading in some browsers Place it as soon after the title as possible: <!doctype…>…<title>I am a title</title><link rel="stylesheet"/>
35. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:More JS Considerations Be aware of VS controls that generate non-standard mark-up: e.g. ListBox, DropDownList, AdRotator and more. As our DBA always reminds us, never trust the client (device).
36. Shawnee County's logo is protected by law. All other presentation content is in the public domain. Brass Tacks:More JS Considerations The JS pseudo-protocol is not a protocol… If you use it or inline event handlers with href="#", the event will not fire in some cases, leaving users bewildered.
