I'm aware there are multiple input types that force different keyboard layouts on mobile devices. Is there an input type or other attribute that will force the input to open to emoji keyboard on focus?
I don't believe there is, as emoji is technically another language keyboard. But I'd love outside validation to make sure this is the case.
You can't for now, there was an issue on github about that : https://github.com/w3c/html/issues/495
