/* 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%
