+### Card decks
+
+Need a set of equal width and height cards that aren't attached to one another? Use card decks. By default, card decks require two wrapping elements: `.card-deck-wrapper` and a `.card-deck`. We use table styles for the sizing and the gutters on `.card-deck`. The `.card-deck-wrapper` is used to negative margin out the `border-spacing` on the `.card-deck`.

 ## Columns
+Just like with card groups, card footers in decks will automatically line up.
 
 Cards can be organized into [Masonry](http://masonry.desandro.com)-like columns with just CSS by wrapping them in `.card-columns`. Cards are ordered from top to bottom and left to right when wrapped in `.card-columns`.
