Is it possible to style the first post of a thread slightly different from the rest?

I'd like to remove the border from this css, only on the first post of every thread though. Does anyone know how I might be able to do that please?

.messageList .message {
border-top: 1px solid #D7E1FC;
}

Add this to EXTRA.css:

.messageList .message:first-child {
border-top: 1px solid #D7E1FC;
}

That will apply to the first post on every page.

Awesome, thank you Brogan

The following code worked.

.messageList .message:first-child {
border-top: none;
}
