Custom template for userdefined contact form

Silverstripe Version:

Question:

Hi, I’m using the userform module to do a contact form. But would like it to look a bit more like Bootstrap Snippet Contact Form With Validation using HTML CSS Bootstrap jQuery this… which i can probably do through heavy amounts of css, or writing my own contact form php i guess.

Was just wondering if someone knew of a way to do a custom template for a userform module so i could mess around with the template externally?

Cheers
