[Plugin: Codepress Admin Columns] How to make a page with .. maybe 2 rows.?

Still new here. When I make a simple static page, it seems that the only general option is like … text with maybe an image floating to the right(and then I am at the bottom of the page). But …..

as like when I layout a normal website page with html & css, I might want a div below, with more content(like 2 rows of content). Generally, how would one do this in WP?

Do I need to hand code it on the page (with external css), or maybe edit page.php or something? Or is there an easy way. I can’t imagine that when people make WP sites to look like normal websites, that the pages are always that short. Any tips would be appreciated. Thanks.
