What's the code for it?

what do you mean by it? you want text overlapping an image or text overlapping text (don't see the point of that really though) ? More info would be usefull :)

if you mean absolute positioning then this is the code:

style="position: absolute; top: #px; left: #px;"

replace #'s with numbers, and put this part into a <div> for example if you want to position text like this:

<div style="position: absolute; top: #px; left: #px;">
text here
</div>

love,
