Contact Form 7 - function/hook to change style of response output?

I'm using Contact Form 7 with WordPress - And up until this point, i've achieved my styling by using HTML tags within Contact Form 7's 'Message' area.

A recent update has removed this ability, and thus strips all HTML from these fields before submission.

As i have a number of sites which follow the same responsive styling, Ideally - all i need to be able to do is wrap the content inside wpcf7-response-output, with another div ideally.

I was just wondering if there's any particular hook/action we can use to alter this styling?

Thanks!
