- HTML5 ancillary materials like tutorials and books provide helpful supplements to the official specification and receive a grade of B. - New HTML5 elements like <video> and <canvas> aim to bring rich media and scripting capabilities to the web in a native way, but browser support varies. - The talk evaluated progress on HTML5 features, tools support, and accessibility, generally finding syntax improvements and new APIs promising but implementation lagging in places.

- 59. getElementsByClassName spec grade: A+
- 60. Interactive & UI elements <details>, <progress>, <meter> spec grade: B+
- 61. New structural elements <article>, <section> grade: B ?
- 62. <canvas> 2D spec grade: B-/D- ?
- 63. <canvas> 3D spec grade: B+/D- ?
- 64. <video> spec grade: B+/C- ?
- 65. Let’s grade some features on how well they are currently supported in browsers
- 66. Example: drag & drop interopability: D- ?
