The class mzp-l-split-media-constrain-height added to the mzp-c-split-media wrapper will make the media scale to fit the height of the container, determined by the amount of content in the body. It will shrink to fit a short container or expand to fit a tall one (but won’t be upscaled beyond the image’s native dimensions).

As with the media overflow option, height-constrained media can overflow if the container is tall, causing part of the image to be hidden, so choose wisely.
