A Bootstrap card component



A general purpose container for grouping related UI elements together with a border and optional padding. To learn more about card()s, see the Cards article or the other articles listed in the References section below.


  full_screen = FALSE,
  height = NULL,
  max_height = NULL,
  min_height = NULL,
  fill = TRUE,
  class = NULL,
  wrapper = card_body,
  id = NULL



Unnamed arguments can be any valid child of an htmltools tag (which includes card items such as card_body(). Named arguments become HTML attributes on returned UI element.


If TRUE, an icon will appear when hovering over the card body. Clicking the icon expands the card to fit viewport size.


Any valid CSS unit (e.g., height="200px"). Doesn't apply when a card is made full_screen (in this case, consider setting a height in card_body()).

max_height, min_height

Any valid CSS unit (e.g., max_height="200px"). Doesn't apply when a card is made full_screen (in this case, consider setting a max_height in card_body()).


Whether or not to allow the card to grow/shrink to fit a fillable container with an opinionated height (e.g., page_fillable()).


Additional CSS classes for the returned UI element.


A function (which returns a UI element) to call on unnamed arguments in ... which are not already card item(s) (like card_header(), card_body(), etc.). Note that non-card items are grouped together into one wrapper call (e.g. given card("a", "b", card_body("c"), "d"), wrapper would be called twice, once with "a" and "b" and once with "d").


Provide a unique identifier for the card() or value_box() to report its full screen state to Shiny. For example, using id = "my_card", you can observe the card's full screen state with input$my_card_full_screen.


A htmltools::div() tag.
