I'm not sure if I understand you correctly but you want to stack around 4 "items" horiztonal and keep stacking them vertically? Something like this:

Section 1 | Section 2 | Section 3 | Section 4
---------------------------------------------------
Section 5 | Section 6 | Section 7 | Section 8

If thats the case, you can setup 2 DIVs width around 800px-1000px or so and *IN* the DIV create 4 more DIVs, one for each section. Finally, repeat the same thing for the bottom section except it will be right under the first 4. Hope this helps. Let me know if you need more help.
