+Bootstrap utilities are generated with our utility API and can be used to modify or extend our default set of utility classes via Sass. Our utility API is based on a series of Sass maps and functions for generating families of classes with various options. If you're unfamiliar with Sass maps, read up on the [official Sass docs](https://sass-lang.com/documentation/values/maps/) to get started.
 
 The `$utilities` map contains all our utilities and is later merged with your custom `$utilities` map, if present. The utility map contains a keyed list of utility groups which accept the following options:
 
 <BsTable class="table table-utilities">
 | Option | Type | Default&nbsp;value | Description |
 | --- | --- | --- | --- |
-| [`property`](#property) | **Required** | – | Name of the property, this can be a string or an array of strings (e.g., horizontal paddings or margins). |
+| [`property`](#property) | **Required** | – | Name of the property, this can be a string or an array of strings (e.g., horizontal paddings or margins). Can also be a map for [property-value mapping](#property-value-mapping). |
 | [`values`](#values) | **Required** | – | List of values, or a map if you don't want the class name to be the same as the value. If `null` is used as map key, `class` is not prepended to the class name. |
-| [`selector`](#selector) | Optional | `class` | Type of CSS selector in the generated CSS ruleset. Can be `class`, `attr-starts`, or `attr-includes`. |
+| [`selector`](#selector) | Optional | `class` | Type of CSS selector in the generated CSS ruleset. Must be `class`, `attr-starts`, or `attr-includes`. Attribute selectors require the `class` option. |
 | [`class`](#class) | Optional | null | Name of the generated class. If not provided and `property` is an array of strings, `class` will default to the first element of the `property` array. If not provided and `property` is a string, the `values` keys are used for the `class` names. |
-| [`css-var`](#css-variable-utilities) | Optional | `false` | Boolean to generate CSS variables instead of CSS rules. |
-| [`css-variable-name`](#css-variable-utilities) | Optional | null | Custom un-prefixed name for the CSS variable inside the ruleset. |
-| [`local-vars`](#local-css-variables) | Optional | null | Map of local CSS variables to generate in addition to the CSS rules. |
+| [`variables`](#variables) | Optional | null | List or map of local CSS variables to generate within the utility's ruleset. If a list, each variable receives the utility value. If a map, uses the provided static values. |
 | [`state`](#states) | Optional | null | List of pseudo-class variants (e.g., `:hover` or `:focus`) to generate. |
 | [`responsive`](#responsive) | Optional | `false` | Boolean indicating if responsive classes should be generated. |
 | [`important`](#importance) | Optional | `false` | Boolean indicating if `!important` should be added to the utility's CSS rules. |
 | [`print`](#print) | Optional | `false` | Boolean indicating if print classes need to be generated. |
-| `rtl` | Optional | `true` | Boolean indicating if utility should be kept in RTL. |

+### Variables
 
-Set the `css-var` boolean option to `true` and the API will generate local CSS variables for the given selector instead of the usual `property: value` rules. Add an optional `css-variable-name` to set a different CSS variable name than the class name.
+Use the `variables` option to generate local CSS custom properties within the utility's ruleset. It accepts either a list or a map.

-### Local CSS variables

-Use the `local-vars` option to specify a Sass map that will generate local CSS variables within the utility class’s ruleset. Please note that it may require additional work to consume those local CSS variables in the generated CSS rules. For example, consider our `.bg-*` utilities:

 ### States
 
-Use the `state` option to generate pseudo-class variations. Example pseudo-classes are `:hover` and `:focus`. When a list of states are provided, classnames are created for that pseudo-class. For example, to change opacity on hover, add `state: hover` and you’ll get `.opacity-hover:hover` in your compiled CSS.
