Content below sidebar

Hi,

I have multiple sidebars where for each I have…

  1. Registered separate widget areas in init.php

  2. Modified sidebar.php to display the correct sidebar depending on the page that is being loaded…
    For example…

    if( is_woocommerce() ) {
    dynamic_sidebar(‘product-single’);
    } else {
    dynamic_sidebar(‘sidebar-primary’);
    }

Is it possible for my product-single sidebar to be a certain height so that I can have content appear below it? I only have a couple of widgets I wish to display so my sidebar is quite short however I have a lot of other content on the page and I cannot make use of the 33% of space that the sidebar consumes.
