Hello all, Below are two simplified versions of a page with a problem I have not been able to solve. www.fundacionalbertoadriani.org.ve/problem.php www.fundacionalbertoadriani.org.ve/problem2.php The css and html code for both versions is exactly the same. The only difference is that problem2.php has a bunch more <p> tags inside the "Libros" block to make it taller. It is clear here that the "Libros" block is creating empty space below the GENIMAGES block thus pushing down the rest of the content. This only happens with Firefox, not with IE. Any clues? Thanks again.
