Ideas on absolute positioning of dynamic content in mobile web app?

Hi,
I'm currently developing a mobile web app using jQuery Mobile and before I get to far deep I'd like to hear your thoughts about using absolute positioning of dynamic content in a mobile web app!

I use it when I need to populate data from database through php and ajax and in this case I think it is convenient to "design" a template page with absolute positioning my divs. I use different class names for all fields I want to replace with my data from ajax using things like:
$(newRow).find(".row_header").text(object.NAME);
...

What's your experience about this?
Thx!
