put Form input fields on same line as label (Restyle registration form)

Hi,

I would like to know how i can put the input fields of the registration form on the same line as the label of the field. Right now it is like this:

Username:
<input field>
Password:
<input field>

This way the form get’s a lot of vertical height because of the amount of fields. So what I am looking for is this:

Username: <input field>
Password: <input field>

I already checked the files in the /template directory of the plugin but I didn’t find a way to change this. Any help would be appreciated.
