It is not possible to setup it using one css for whole content if you use muffin builder items because some of texts that you probably need won`t be in p tag. But you can use below css and if this won`t work for some items on your website where it should be, then you must make similar css for all items where you want this line height.
p { line-height: 32px; }
Above code will definitely work for all texts wrapped into p tag.
