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: - -{{< bs-table "table text-start" >}} -| Option | Type | Description | -| --- | --- | --- | -| `property` | **Required** | Name of the property, this can be a string or an array of strings (e.g., horizontal paddings or margins). | -| `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, it isn't compiled. | -| `class` | Optional | Variable for the class name if you don't want it to be the same as the property. In case you don't provide the `class` key and `property` key is an array of strings, the class name will be the first element of the `property` array. | -| `state` | Optional | List of pseudo-class variants like `:hover` or `:focus` to generate for the utility. No default value. | -| `responsive` | Optional | Boolean indicating if responsive classes need to be generated. `false` by default. | -| `rfs` | Optional | Boolean to enable fluid rescaling. Have a look at the [RFS]({{< docsref "/getting-started/rfs" >}}) page to find out how this works. `false` by default. | -| `print` | Optional | Boolean indicating if print classes need to be generated. `false` by default. | -| `rtl` | Optional | Boolean indicating if utility should be kept in RTL. `true` by default. | -{{< /bs-table >}} - -## API explained - -All utility variables are added to the `$utilities` variable within our `_utilities.scss` stylesheet. Each group of utilities looks something like this: - -```scss -$utilities: ( - "opacity": ( - property: opacity, - values: ( - 0: 0, - 25: .25, - 50: .5, - 75: .75, - 100: 1, - ) - ) - ); -``` - -Which outputs the following: - -```css -.opacity-0 { opacity: 0; } -.opacity-25 { opacity: .25; } -.opacity-50 { opacity: .5; } -.opacity-75 { opacity: .75; } -.opacity-100 { opacity: 1; } -``` - -### Custom class prefix - -Use the `class` option to change the class prefix used in the compiled CSS: - -```scss -$utilities: ( - "opacity": ( - property: opacity, - class: o, - values: ( - 0: 0, - 25: .25, - 50: .5, - 75: .75, - 100: 1, - ) - ) - ); -``` - -Output: - -```css -.o-0 { opacity: 0; } -.o-25 { opacity: .25; } -.o-50 { opacity: .5; } -.o-75 { opacity: .75; } -.o-100 { opacity: 1; } -``` - -### States - -Use the `state` option to generate pseudo-class variations. Example pseudo-classes are `:hover` and `:focus`. When a list of states are provided, classnames are created for that pseudo-class. For example, to change opacity on hover, add `state: hover` and you'll get `.opacity-hover:hover` in your compiled CSS. - -Need multiple pseudo-classes? Use a space-separated list of states: `state: hover focus`. - -```scss -$utilities: ( - "opacity": ( - property: opacity, - class: opacity, - state: hover, - values: ( - 0: 0, - 25: .25, - 50: .5, - 75: .75, - 100: 1, - ) - ) -); -``` - -Output: - -```css -.opacity-0-hover:hover { opacity: 0 !important; } -.opacity-25-hover:hover { opacity: .25 !important; } -.opacity-50-hover:hover { opacity: .5 !important; } -.opacity-75-hover:hover { opacity: .75 !important; } -.opacity-100-hover:hover { opacity: 1 !important; } -``` - -### Responsive utilities - -Add the `responsive` boolean to generate responsive utilities (e.g., `.opacity-md-25`) across [all breakpoints]({{< docsref "/layout/breakpoints" >}}). - -```scss -$utilities: ( - "opacity": ( - property: opacity, - responsive: true, - values: ( - 0: 0, - 25: .25, - 50: .5, - 75: .75, - 100: 1, - ) - ) - ); -``` - -Output: - -```css -.opacity-0 { opacity: 0 !important; } -.opacity-25 { opacity: .25 !important; } -.opacity-50 { opacity: .5 !important; } -.opacity-75 { opacity: .75 !important; } -.opacity-100 { opacity: 1 !important; } - -@media (min-width: 576px) { - .opacity-sm-0 { opacity: 0 !important; } - .opacity-sm-25 { opacity: .25 !important; } - .opacity-sm-50 { opacity: .5 !important; } - .opacity-sm-75 { opacity: .75 !important; } - .opacity-sm-100 { opacity: 1 !important; } -} - -@media (min-width: 768px) { - .opacity-md-0 { opacity: 0 !important; } - .opacity-md-25 { opacity: .25 !important; } - .opacity-md-50 { opacity: .5 !important; } - .opacity-md-75 { opacity: .75 !important; } - .opacity-md-100 { opacity: 1 !important; } -} - -@media (min-width: 992px) { - .opacity-lg-0 { opacity: 0 !important; } - .opacity-lg-25 { opacity: .25 !important; } - .opacity-lg-50 { opacity: .5 !important; } - .opacity-lg-75 { opacity: .75 !important; } - .opacity-lg-100 { opacity: 1 !important; } -} - -@media (min-width: 1200px) { - .opacity-xl-0 { opacity: 0 !important; } - .opacity-xl-25 { opacity: .25 !important; } - .opacity-xl-50 { opacity: .5 !important; } - .opacity-xl-75 { opacity: .75 !important; } - .opacity-xl-100 { opacity: 1 !important; } -} - -@media (min-width: 1400px) { - .opacity-xxl-0 { opacity: 0 !important; } - .opacity-xxl-25 { opacity: .25 !important; } - .opacity-xxl-50 { opacity: .5 !important; } - .opacity-xxl-75 { opacity: .75 !important; } - .opacity-xxl-100 { opacity: 1 !important; } -} -``` - -### Changing utilities - -Override existing utilities by using the same key. For example, if you want additional responsive overflow utility classes, you can do this: - -```scss -$utilities: ( - "overflow": ( - responsive: true, - property: overflow, - values: visible hidden scroll auto, - ), -); -``` - -### Print utilities - -Enabling the `print` option will **also** generate utility classes for print, which are only applied within the `@media print { ... }` media query. - -```scss -$utilities: ( - "opacity": ( - property: opacity, - print: true, - values: ( - 0: 0, - 25: .25, - 50: .5, - 75: .75, - 100: 1, - ) - ) - ); -``` - -Output: - -```css -.opacity-0 { opacity: 0 !important; } -.opacity-25 { opacity: .25 !important; } -.opacity-50 { opacity: .5 !important; } -.opacity-75 { opacity: .75 !important; } -.opacity-100 { opacity: 1 !important; } - -@media print { - .opacity-print-0 { opacity: 0 !important; } - .opacity-print-25 { opacity: .25 !important; } - .opacity-print-50 { opacity: .5 !important; } - .opacity-print-75 { opacity: .75 !important; } - .opacity-print-100 { opacity: 1 !important; } -} -``` - -## Importance - -All utilities generated by the API include `!important` to ensure they override components and modifier classes as intended. You can toggle this setting globally with the `$enable-important-utilities` variable (defaults to `true`). - -## Using the API - -Now that you're familiar with how the utilities API works, learn how to add your own custom classes and modify our default utilities. - -### Add utilities - -New utilities can be added to the default `$utilities` map with a `map-merge`. Make sure our required Sass files and `_utilities.scss` are imported first, then use the `map-merge` to add your additional utilities. For example, here's how to add a responsive `cursor` utility with three values. - -```scss -@import "bootstrap/scss/functions"; -@import "bootstrap/scss/variables"; -@import "bootstrap/scss/utilities"; - -$utilities: map-merge( - $utilities, - ( - "cursor": ( - property: cursor, - class: cursor, - responsive: true, - values: auto pointer grab, - ) - ) -); -``` - -### Modify utilities - -Modify existing utilities in the default `$utilities` map with `map-get` and `map-merge` functions. In the example below, we're adding an additional value to the `width` utilities. Start with an initial `map-merge` and then specify which utility you want to modify. From there, fetch the nested `"width"` map with `map-get` to access and modify the utility's options and values. - -```scss -@import "bootstrap/scss/functions"; -@import "bootstrap/scss/variables"; -@import "bootstrap/scss/utilities"; - -$utilities: map-merge( - $utilities, - ( - "width": map-merge( - map-get($utilities, "width"), - ( - values: map-merge( - map-get(map-get($utilities, "width"), "values"), - (10: 10%), - ), - ), - ), - ) -); -``` - -#### Enable responsive - -You can enable responsive classes for an existing set of utilities that are not currently responsive by default. For example, to make the `border` classes responsive: - -```scss -@import "bootstrap/scss/functions"; -@import "bootstrap/scss/variables"; -@import "bootstrap/scss/utilities"; - -$utilities: map-merge( - $utilities, ( - "border": map-merge( - map-get($utilities, "border"), - ( responsive: true ), - ), - ) -); -``` - -This will now generate responsive variations of `.border` and `.border-0` for each breakpoint. Your generated CSS will look like this: - -```css -.border { ... } -.border-0 { ... } - -@media (min-width: 576px) { - .border-sm { ... } - .border-sm-0 { ... } -} - -@media (min-width: 768px) { - .border-md { ... } - .border-md-0 { ... } -} - -@media (min-width: 992px) { - .border-lg { ... } - .border-lg-0 { ... } -} - -@media (min-width: 1200px) { - .border-xl { ... } - .border-xl-0 { ... } -} - -@media (min-width: 1400px) { - .border-xxl { ... } - .border-xxl-0 { ... } -} -``` - -#### Rename utilities - -Missing v4 utilities, or used to another naming convention? The utilities API can be used to override the resulting `class` of a given utility—for example, to rename `.ms-*` utilities to oldish `.ml-*`: - -```scss -@import "bootstrap/scss/functions"; -@import "bootstrap/scss/variables"; -@import "bootstrap/scss/utilities"; - -$utilities: map-merge( - $utilities, ( - "margin-start": map-merge( - map-get($utilities, "margin-start"), - ( class: ml ), - ), - ) -); -``` - -### Remove utilities - -Remove any of the default utilities by setting the group key to `null`. For example, to remove all our `width` utilities, create a `$utilities` `map-merge` and add `"width": null` within. - -```scss -@import "bootstrap/scss/functions"; -@import "bootstrap/scss/variables"; -@import "bootstrap/scss/utilities"; - -$utilities: map-merge( - $utilities, - ( - "width": null - ) -); -``` - -#### Remove utility in RTL - -Some edge cases make [RTL styling difficult](https://rtlstyling.com/posts/rtl-styling#common-things-that-might-not-work-for-rtl), such as line breaks in Arabic. Thus utilities can be dropped from RTL output by setting the `rtl` option to `false`: - -```scss -$utilities: ( - "word-wrap": ( - property: word-wrap word-break, - class: text, - values: (break: break-word), - rtl: false - ), -); -``` - -Output: - -```css -/* rtl:begin:remove */ -.text-break { - word-wrap: break-word !important; - word-break: break-word !important; -} -/* rtl:end:remove */ -``` - -This doesn't output anything in RTL, thanks to [the RTLCSS `remove` control directive](https://rtlcss.com/learn/usage-guide/control-directives/#remove). |
