An old question but deserves an update as now there is a way.

The correct CSS based answer is to use object-fit: cover, which works like background-size: cover. Positioning would be taken care of by object-position attribute, which defaults to centering.

But there is no support for it in any IE / Edge browsers, or Android < 4.4.4. Also, object-position is not supported by Safari, iOS or OSX. Polyfills do exist, object-fit-images seems to give best support.

For more details on how the property works, see CSS Tricks article on object-fit for explanation and demo.
