The W3C recently created a controversy by releasing an HTML5 logo. In the process, they lumped a few other technologies under the heading HTML5 that really are not HTML. I thought a little visual might help you see what parts of all those things the W3C included really are HTML5.
| Technology | HTML5 | NOT |
|---|---|---|
| HTML | X | |
| CSS 3 | X | |
| SVG | X | |
| WOFF | X | |
| GRAPHICS, 3D & EFFECTS | X | |
| MULTIMEDIA | X* |
*the new <video> and <audio> elements are HTML5. Not all multimedia is.
