How to make the Phone Number field and Email Address field in line with each other

How do I format my form so that I have two "form text boxes" side-by-side instead of on 2 lines?  

for example:   

Phone: _____________    Email address:______________

instead of

Phone:________________

Email address: ________________

To make the fields in your form appear side-by-side or in columns, please see this guide — Setting-up-Form-Columns
