CSS to get Tabs Stacked Vertically Beside the Content

It works fine with the standard version and with the <a href="https://github.com/petelove666/Responsive-Tabs/pull/4">modification</a> proposed by <a href="https://github.com/ajmueller">ajmueller</a> (to enable tab list items to contain HTML content).

Perhaps some adjustments of the widths (list and panel) will be needed depending on the breakpoints you have.
