Managed to change font on form for 99%

I have been looking through the support forum have managed to enter a short code which I found on the plugin’s support thread and that solved my problem for 99%. This is the code I used and I enter it at the end of the plugin’s style sheet:

div.cscfForm label {
	font-family: 'Lato', sans-serif; font-weight: 400; color: #333; line-height: 140%;
	font-style:sans-serif;
}

But now there still is one single line on the top of the page which isn’t responding to the new CSS. The rest of the form does.
You can find it on: http://www.biancabenson.com/contact/
So how do I change the CSS so the entire page responds to it?
