I have a 2 column layout and want the right column (sidebar) to be the same entire height of the 'container' block that holds the content. I've modified sidebar.php in my child theme to wrap a div before and after the content (primary, secondary...).
That works great but I can't style the new div properly in order to force it to be the same height as the 'container' block. I've tried min-height: 100% but that seems to have done nothing whatsoever.
