= Caption Category Keys
:description: Reference list of the available global caption category keys and their value types.
:navtitle: Caption
:source-language: yaml
The keys in the `caption` category control the arrangement and style of block captions globally.
In addition to this global `caption` category, each of the keys listed below, except for the `text-decoration` keys, can be set on the caption key nested inside the following block categories: `code`, `example`, `footnotes`, `image`, `quote`, `table`, and `verse`.
TIP: The `caption-align` and `caption-text-align` keys, when nested on the `image` or `table` category, also accept the value `inherit`.
See xref:block-images.adoc[] and xref:tables.adoc[] for more information about setting `inherit` on their captions.
