In July 2017 flexbox support is at 97.48% (prefixed). In the past, the sticky footer element has relied on absolute positioning and a fixed height. The utility of a fixed height footer is fairly limited, not to mention the unsightly mess created when the footer expands beyond the predetermined fixed height.
With the use of flexbox, the sticky footer example CSS becomes lighter and the sticky footer element's height can be auto.
