For others to know, this is what andrew was talking about, which is a great idea!
#yourcontactformID a-pre-existing-tag {
margin: 230em 0.5em 1em;
padding: 0.2em 1em;
color:#000;
}
ex:
#wpcf7-f443-p440-o1 div.wpcf7-response-output {
margin: 230em 0.5em 1em;
padding: 0.2em 1em;
color:#000;
}
worked like a charm for me! :)
