Can the black lettering be changed to white?

Once I type my email address in the "Email Validator" and press "Verify Email" there's an automated black lettering statement that appears. The lettering is too dark with the purple background (see attached image example). I would like the black letting to be white lettering. How can I do this?

I have also included a live link to the page below.

Thank you.

You can add custom CSS to your widgets from the widget settings. You can follow this tutorial.

If you want texts to be white, you can add:

body { color: white; }

to the Custom CSS tab, which will make the text in the email verify widget white.

If you need anything else, feel free to reply here.

Before contacting you I did read the tutorial but it was somewhat confusing.

Thanks for the code. I'll try it now.
