Hey there,
it would be great, if you could add the following html 5 tags to the input fields:

E.g. <input type="tel"> for the telephone number tells the browser on mobile devices to open a specific keyboard for numbers,
the same for
<input type="email"> for a keyboard with an @ button.
What do you think about that? :)
That way you could even more optimize gravity forms for mobile devices.
Best regards,
Marko
