/* Sticky footer */

/**

 * Basic idea: https://philipwalton.github.io/solved-by-flexbox/demos/sticky-footer/

 * Details: https://github.com/philipwalton/solved-by-flexbox/blob/master/assets/css/components/site.css

 *

 * .Site -> body > .container

 * .Site-content -> body > .container .row

 * .footer -> footer

 *

 * Key idea seems to be to ensure that .container and __all its parents__

 * have height set to 100%

 *
