Saying it's not a real thing is kind of silly. If some browsers are supporting it, how is it not real?
Again, I didn't go specifically to that site, I simply googled it because I was fairly sure I've seen that type used before. I actually checked gotapi.com first but didn't see it there, so I googled.
The second link I provided backs it up, and also references https://developer.apple.com/library/safari/#codinghowtos/Mobile/UserExperience/_index.html
It sounds like you're saying that because one source I used should *NEVER* be used in your opinion, that invalidates the fact that it's actually quite accurate. The w3schools page itself says "Note: Not all major browsers support all the new input types. However, you can already start using them; If they are not supported, they will behave as regular text fields." which is the same thing you said.
So explain to me why because you guys hate this one site, that says the same thing as many other sites, my point that it's a valid input type in HTML5 is wrong?
