How to set the height of a desired block if the clearfix doesn't help.

Help forum, made gallery (.production)but it has zero height - the feeling that the float is made, although the documentation says that the Flex grids. And because of this, the block methods under productionswhere the mistake was made?
https://goreska.github.io/ - check the block productions, clearfix doesn't help if you apply it to the jqery plug - in box is the right height, but the plugin stops working.
Plugin - galereya - vodkabears.github.io/galereya
PS: so ask clearfix height standards, but the plugin dies.
