I can’t see an option to align the text to the top of the box? Also when you press enter it submits the form rather than moving down to the next box.
Please elaborate more on this.
Have you made your own contact form or are you using a contact us form through Wix Forms?
Did you simply add a user input box for the user to fill in or did you use the Address Input as stated here.

If you have made up your own, then have you used any code on your page as this is the Corvid Forum which deals with all code related issues.
If it is just about a design issue then you can change these settings in the elements own settings in the Editor itself.
