How do I position a dynamically created element on a web page using Javascript?

[blakemckenna]

I've created a simple contact page and want to add a little flair to it. I've created a dynamic element but I don't know what properties of a DOM object to use for element placement. The image below is my Contact form. All I want to do is when I click within one of the input fields is move the text that is already in their to just above and the textbox. I would like to do it with animation also but that I could probably figure out.

Thanks
