How to get text above my chat.

Okay, I have added a new java script page on my home page with a new chat, here is the code.

Code:

function insertChatBox(chatbox_id, chatbox_url) {
    return insertChatBoxNew(chatbox_id, chatbox_url);
}

function insertChatBoxNew(chatbox_id, chatbox_url) {

   document.getElementById(chatbox_id).innerHTML = '<iframe src="http://aurenjs.com/chat.php?id=spike" id="frame_chatbox" scrolling="no" width="100%" height="100%" marginwidth="0" marginheight="0" frameborder="0"></iframe>';
}

How would I make some text about it in the center like this:

Also how would I lower the chat down a little bit to fit it in, if so please tell me all of the code I need to add.

Thanks!
