Aligning the email field

Hi

I have tried everything to align center the email field.

I have added this in the Form Markup:

<p style="text-align:center;">
<label><strong>Subscribe to Receive our Special Offer:</strong></label>

<input type="email" id="mc4wp_email" name="EMAIL" placeholder="Your email address" required />

<input type="submit" value="Subscribe" /></p>

But it only aligns the label and the submit button center, leaving the email field aligned left?

I’ve tried various CSS codes but I haven’t succeeded.

Please help.
