What is Not HTML5

People can be forgiven for assuming that awesome JavaScript-less transitions are grouped into the all-encompassing HTML5. Hey -- even Apple has inadvertently promoted this idea. For non-developers, who cares; it's an easy way to refer to modern web standards. However, for us, though it may just be semantics, it's important to understand exactly what is not HTML5.

1. SVG: Not HTML5. It's at least five years old.
2. CSS3: Not HTML5. It's...CSS.
3. Geolocation: Not HTML5.
4. Client Storage: Not HTML5. It was at one point, but was removed from the spec, due to the fact that many worried that it, as a whole, was becoming too complicated. It now has its own specification.
5. Web Sockets: Not HTML5. Again, was exported to its own specification.

Regardless of how much distinction you require, all of these technologies can be grouped into the modern web stack. In fact, many of these branched specifications are still managed by the same people.
