This changeset introduces functions `wp_get_global_styles_custom_css()` and `wp_enqueue_global_styles_custom_css()`, which allow accessing and enqueuing custom CSS added via global styles. Custom CSS via global styles is handled separately from custom CSS via the Customizer. If a site uses both features, the custom CSS from both sources will be loaded. The global styles custom CSS is then loaded after the Customizer custom CSS, so if there are any conflicts between the rules, the global styles take precedence. Similarly to e.g. [55185], the result is cached in a non-persistent cache, except when `WP_DEBUG` is on to avoid interrupting the theme developer's workflow. Props glendaviesnz, oandregal, ntsekouras, mamaduka, davidbaumwald, hellofromtonya, flixos90. Fixes #57536.

/**
|
|
* Presets are a set of values that serve
|
|
* to bootstrap some styles: colors, font sizes, etc.
|
|
*
|
|
* They are a unkeyed array of values such as:
|
|
*
|
|
* ```php
|
|
* array(
|
|
* array(
|
|
* 'slug' => 'unique-name-within-the-set',
|
|
* 'name' => 'Name for the UI',
|
|
* <value_key> => 'value'
|
|
* ),
|
|
* )
|
|
* ```
|
|
*
|
|
* This contains the necessary metadata to process them:
|
|
*
|
|
* - path => Where to find the preset within the settings section.
|
|
* - prevent_override => Disables override of default presets by theme presets.
|
|
* The relationship between whether to override the defaults
|
|
* and whether the defaults are enabled is inverse:
|
|
* - If defaults are enabled => theme presets should not be overriden
|
|
* - If defaults are disabled => theme presets should be overriden
|
|
* For example, a theme sets defaultPalette to false,
|
|
* making the default palette hidden from the user.
|
|
* In that case, we want all the theme presets to be present,
|
|
* so they should override the defaults by setting this false.
|
|
* - use_default_names => whether to use the default names
|
|
* - value_key => the key that represents the value
|
|
* - value_func => optionally, instead of value_key, a function to generate
|
|
* the value that takes a preset as an argument
|
|
* (either value_key or value_func should be present)
|
|
* - css_vars => template string to use in generating the CSS Custom Property.
|
|
* Example output: "--wp--preset--duotone--blue: <value>" will generate as many CSS Custom Properties as presets defined
|
|
* substituting the $slug for the slug's value for each preset value.
|
|
* - classes => array containing a structure with the classes to
|
|
* generate for the presets, where for each array item
|
|
* the key is the class name and the value the property name.
|
|
* The "$slug" substring will be replaced by the slug of each preset.
|
|
* For example:
|
|
* 'classes' => array(
|
|
* '.has-$slug-color' => 'color',
|
|
* '.has-$slug-background-color' => 'background-color',
|
|
* '.has-$slug-border-color' => 'border-color',
|
|
* )
|
|
* - properties => array of CSS properties to be used by kses to
|
|
* validate the content of each preset
|
|
* by means of the remove_insecure_properties method.
|
|
*
|
|
* @since 5.8.0
|
|
* @since 5.9.0 Added the `color.duotone` and `typography.fontFamilies` presets,
|
|
* `use_default_names` preset key, and simplified the metadata structure.
|
|
* @since 6.0.0 Replaced `override` with `prevent_override` and updated the
|
|
* `prevent_override` value for `color.duotone` to use `color.defaultDuotone`.
|
|
* @since 6.2.0 Added 'shadow' presets.
