Formit responsive

I’m using Formit to create contact forms. Is it possible to have an responsive contact form, so it shows full width on mobile? And perhaps max width on desktop?
input fields and textarea’s tend to have different widths by nature; I need them to be same width.

This would be achieved through your own form HTML markup.

Do you use a responsive CSS framework, such as Bootstrap, Foundation etc?

They make this sort of thing a lot more straightforward and both have controls for responsive widths and for standardising form elements

It’s Bootstrap. I’m aware off the responsive elements, but I’m specifically struggling with the form. It looks like the fields have some fixed width.

Do you know the Bootstrap version?

Are you able to share your form code?
