Is there an HTML code out there like this?

Asked by Quicky (1) August 15th, 2008 from iPhone

I’m looking for something that all I have to do is create a simple black box and a smaller text box under it with just a submit button and no design. So what I need is a code that allows the text that was entered into the bottom text area to be entered in the black square above. Basically an extremely slimmed down chat room. If it makes sense I just mean everything entered in the small box on the bottom goes into the bigger box above. (sorry if I don’t make sense, Im listening to music watching tv and surfing the web while asking this on my iPod)
