title: How to maintain aspect ratio of responsive card image with minimum height?
body: <p>Using react-bootstrap how can you make a Card background image fill the whole card, yet enforce a minimum height without squashing the image?  I want Bootstrap to downsize the image until the minimum height is reached, then crop the image if required to maintain the minimum height, all while maintaining the image's aspect ratio (ie: without squashing the image).</p>
