why isn't the padding the same between recaptcha and submit button?

do you have a <p></p> around the reCaptcha?

by default it just adds
[recaptcha]

The reCaptcha is an iframe pulled from Google and won’t have p tag styling

Yes i did add P tags. Still the same. Any other clue?

I have the same problem as worldsdream, it amazes me how the hard things can be quite simple, but resolving the seemingly simple things can be difficult to trackdown a solution

You may target the wrapper around iframe
see https://stackoverflow.com/questions/27713505/recaptcha-api-v2-styling.

For a basic* styling around reCAPTCHA, you may do something like this

.wpcf7-recaptcha{
?
    margin-top: 20px;
    margin-bottom: 20px;

}???????

Use Firebug or Chrome Dev Tools to examine the HTML and CSS of your CF7 form in detail. Once you understand how the HTML and CSS is configured in your CF7 form, you should be able to see the CSS changes you need to change the appearance of the form to suit your requirements.??
