 Cards include various options for customizing their backgrounds, borders, and color.
 
-### Dark cards
+### Background and color
 
-By default, cards use dark text and assume a light background. You can reverse that by toggling the `color` of text within, as well as that of the card's subcomponents, with `.card-dark`. Then, specify a dark `background-color` and `border-color` to go with it.
-
-You can also use `.card-dark` with the [contextual backgrounds variants](#background-variants).
+Use [text and background utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/colors/) to change the appearance of a card.

-### Outline cards
+### Border
 
-In need of a colored card, but not the hefty background colors they bring? Replace the default modifier classes with the `.card-outline-*` ones to style just the `border-color` of a card.
+Use [border utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/borders/) to change just the `border-color` of a card. Note that you can put `.text-{color}` classes on the parent `.card` or a subset of the card's contents as shown below.

+You can also change the borders on the card header and footer as needed, and even remove their `background-color` with `.bg-transparent`.
