I've searched through the forums here and can't find any specific code to adjust the height on the sidebar for the Twenty Thirteen theme. I realize this is part of the the design, but I'd rather not have the sidebar (showing the Secondary Widget Area content) overlap the footer like it is. It seems like a simple fix, but I've been spending a ton of time scanning the forums and racking my brain thinking of a way to prevent this from happening. I'd just like to the capability of specifying the height I want or forcing the footer area to go below the sidebar content.
Here's a link to the page I'm trying to fix: http://thescotchpine.com/support/
Side note: I installed a plugin I found out about in one of the forums that allows me to display the sidebar content on whatever page I want (this was a huge time saver as I was going to try and figure out how to create a custom template so it wouldn't show on the home page). I'm using a plugin called Content Aware Sidebars.
Anyway, any help would be greatly appreciated. And, if it just doesn't look like there's an easy CSS or .PHP code fix...we'll either live with the sidebar overlapping the footer as is or just do away with the sidebar altogether and place that info in the main content section. Just trying to customize this cool WordPress theme a little ;-)
