* Presets are a set of values that serve

[71] Fix | Delete

* to bootstrap some styles: colors, font sizes, etc.

[72] Fix | Delete

*

[73] Fix | Delete

* They are a unkeyed array of values such as:

[74] Fix | Delete

*

[75] Fix | Delete

* array(

[76] Fix | Delete

* array(

[77] Fix | Delete

* 'slug' => 'unique-name-within-the-set',

[78] Fix | Delete

* 'name' => 'Name for the UI',

[79] Fix | Delete

* <value_key> => 'value'

[80] Fix | Delete

* ),

[81] Fix | Delete

* )

[82] Fix | Delete

*

[83] Fix | Delete

* This contains the necessary metadata to process them:

[84] Fix | Delete

*

[85] Fix | Delete

* - path => Where to find the preset within the settings section.

[86] Fix | Delete

* - prevent_override => Disables override of default presets by theme presets.

[87] Fix | Delete

* The relationship between whether to override the defaults

[88] Fix | Delete

* and whether the defaults are enabled is inverse:

[89] Fix | Delete

* - If defaults are enabled => theme presets should not be overridden

[90] Fix | Delete

* - If defaults are disabled => theme presets should be overridden

[91] Fix | Delete

* For example, a theme sets defaultPalette to false,

[92] Fix | Delete

* making the default palette hidden from the user.

[93] Fix | Delete

* In that case, we want all the theme presets to be present,

[94] Fix | Delete

* so they should override the defaults by setting this false.

[95] Fix | Delete

* - use_default_names => whether to use the default names

[96] Fix | Delete

* - value_key => the key that represents the value

[97] Fix | Delete

* - value_func => optionally, instead of value_key, a function to generate

[98] Fix | Delete

* the value that takes a preset as an argument

[99] Fix | Delete

* (either value_key or value_func should be present)

[100] Fix | Delete

* - css_vars => template string to use in generating the CSS Custom Property.

[101] Fix | Delete

* Example output: "--wp--preset--duotone--blue: <value>" will generate as many CSS Custom Properties as presets defined

[102] Fix | Delete

* substituting the $slug for the slug's value for each preset value.

[103] Fix | Delete

* - classes => array containing a structure with the classes to

[104] Fix | Delete

* generate for the presets, where for each array item

[105] Fix | Delete

* the key is the class name and the value the property name.

[106] Fix | Delete

* The "$slug" substring will be replaced by the slug of each preset.

[107] Fix | Delete

* For example:

[108] Fix | Delete

* 'classes' => array(

[109] Fix | Delete

* '.has-$slug-color' => 'color',

[110] Fix | Delete

* '.has-$slug-background-color' => 'background-color',

[111] Fix | Delete

* '.has-$slug-border-color' => 'border-color',

[112] Fix | Delete

* )

[113] Fix | Delete

* - properties => array of CSS properties to be used by kses to

[114] Fix | Delete

* validate the content of each preset

[115] Fix | Delete

* by means of the remove_insecure_properties method.

[116] Fix | Delete

*

[117] Fix | Delete

* @since 5.8.0

[118] Fix | Delete

* @since 5.9.0 Added the `color.duotone` and `typography.fontFamilies` presets,

[119] Fix | Delete

* `use_default_names` preset key, and simplified the metadata structure.

[120] Fix | Delete

* @since 6.0.0 Replaced `override` with `prevent_override` and updated the

[121] Fix | Delete

* `prevent_override` value for `color.duotone` to use `color.defaultDuotone`.

[122] Fix | Delete

* @since 6.2.0 Added 'shadow' presets.

[123] Fix | Delete

* @since 6.3.0 Replaced value_func for duotone with `null`. Custom properties are handled by class-wp-duotone.php.

[124] Fix | Delete

* @since 6.6.0 Added the `dimensions.aspectRatios` and `dimensions.defaultAspectRatios` presets.

[125] Fix | Delete

* Updated the 'prevent_override' value for font size presets to use 'typography.defaultFontSizes'

[126] Fix | Delete
