Format and position Generic fields

Hello, I would like to integrate Generic in my Cred-2 form fields date.
These two fields are to be positioned side by side in the same amount. Similarly, the label at the same level with the icons date. How should look like the HTML and CSS code?

The link to the form: http://www.womo-reisen.de/stellplatz-melden/

Thank you very much
