here is some sode you could use of you wanted to use frames:
<frameset rows="100,*" frameborder="0">
<frame name="top_frame" src="top.html" scrolling="no" noresize frameborder="0">
<frame name="bottom_frame" src="bottom.html" frameborder="0">
</frameset>
the "100,*" part sais the sizes of the frmaes, in this case, the top one is 100px hight, and the bottom one fills the rest of the page. if you want colloms rather then rows, change is to cols.
