Jotform: Multiple fields per row

Hi- I have two questions:
1. How do I create form that can have two fields per row, for example, phone and email, see attached.
2. Is it possible to embed the field's description in the text box, see attached.

To add a description to each field simply click on the field and add the description in the "Hover Text" option:
