Styling the widget button to match my site

The developer of the theme I’m using helped me resolve this by providing the code I needed and telling me where to put it.

I’m also struggling with this, I’ve managed to style the inputs but not the button. Any help would be greatly appreciated

Its OK, I sused it myself.

#wp_email_capture input.wp-email-capture-submit
{

}

or for on page:

#wp_email_capture_2 input.wp-email-capture-submit
{

}
