- 78. HTML5 Feature Areas Semantics: Markup describes purpose of content(e.g. <header> vs. <div class="header">) CSS3: New selectors, more visual options Multimedia: <audio> and <video> Graphics: <canvas> and in-line SVG
- 79. HTML5 Feature Areas Device Access: Geolocation, accelerometer, etc. Performance: Run JS in background Offline/Storage: Use web apps on/off line Connectivity: Improved XHR, SSE, WebSockets
- 80. Semantic Markup & Microdata
- 82. Why don’t you serve it with the right mime type?
- 83. Over 90% of XHTML is delivered with the text/html mime type and therefore broken
- 87. HTML5 allows XML syntax from XHTML 1.0 for backward compatibility
- 88. For example: <br />
- 89. HTML5 has well-definedprocessing ruleshttp://validator.nu
- 90. New HTML5 Elements <canvas> <article> <audio> <aside> <command> <dialog> <details> <datalist> <header> <hgroup> <footer> <figure> <embed> <nav> <keygen> <mark> <meter> <ruby> <output> <section> <rp> <rt> <video> <source> http://dev.w3.org/html5/markup/elements.html#elements
- 91. Removed Elements <acronym> <basefont> <applet> <big> <dir> <font> <center> <s> <strike> <frame> <u> <frameset> <noframes> <tt>

- 105. Search, e-mail, web address
- 107. Spin boxes and sliders
- 108. Features degrade gracefully (unknown input types are treated as text)
- 109. Benefits:
- 112. Forms features Date picker Color picker
- 113. CSS3
- 115. Almost 50 modules (readiness varies)
- 116. Use browser-specific prefixes until finalized
- 118. Examples:

- 120. Gradients
- 121. Multi-column layout
- 122. Reflection
