* - value_key => the key that represents the value
|
|
* - value_func => the callback to render the value (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.
|
|
* Each key is a template string to resolve similarly to the css_vars and each value is the CSS property to use for that class.
|
|
* Example output: ".has-blue-color { color: <value> }"
|
|
* - properties => a list of CSS properties to be used by kses to check the preset value is safe.
