Align center the text under Submit button and one more thing

Hello,

I need to have the text “This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply.” to be align center under the Submit button on the phone screens.

I did the submit and text in Contact 7 form as this:

<div class="column">
[submit "Wy?lij"]
</div>

<div class="cloumn">
<p align=""><small>This site is protected by reCAPTCHA and the Google <a href="https://policies.google.com/privacy">Privacy Policy</a> and <a href="https://policies.google.com/terms">Terms of Service</a> apply.
</p></small>
</div>

And here is some of my CSS:

@media only screen and (max-width:767px) {
    input.wpcf7-form-control.wpcf7-submit {
        display: block;
        margin: auto;
    }
}

.column {
	float:left;
	padding:5px;
}

	@media only screen and (max-width:767px) {
    div.column {
			width:100%;
		}}

Also do you know how to reduce the space between the Submit and the text on mobile screens?

Please guys help me, because I’m getting tired because of all of this code.
