I assumed maintenance responsibilities for a site built on the Genesis framework, with a Prose child theme, and I would like to fix the disappearing sidebar (gets pushed down on smaller screens), but I am not familiar with how to work with plug-in/widgeted sidebars. The only way I see that I could get a responsive width site would be to change themes, but that would lose some custom design that my client wants to keep
It really is a simple site(not worth all the customization, I don't think), and I have exported its contents into two different themes, both of which seem like decent replacements with better formatting. I was told by the web-designer who created the site that she had stopped using Prose a while back because it wasn't flexible enough. About addressing the sidebar problem, she said, "All sites, responsive sites, automatically drop the sidebar to the bottom of the page. The only way around that is to use css media queries to style a different layout for each screen size. This means basically making 6 renditions of a website."
The site giving me trouble is equinoxpdx.com and the demo sites I prepared to try to fix the disappearing sidebar issue, are at equinoxdemo2.wordpress.com, and equinoxdemo3.wordpress.com.
