Recruiters: Don't say HTML5, you probably don't mean it

Crux of the issue right here:

I’ve thought a lot about why HTML5 became the codeword for CSS3. I think it stems back to the decision by iOS to ban Flash. iOS friendly web pages needed to use HTML5 instead of flash, so the term “HTML5” came to represent everything that came along with mobile friendly websites. That includes responsive design, and animations that run smoothly without a lot of power. Both those things are in the domain of CSS3, not HTML5.

HTML5, to me, is all the wonderful new JavaScript APIs, but I'm an idiot. I've never considered "HTML5" to be anywhere near synonymous with CSS3, but I'm an idiot.
