This is a low-level API that may need to do breaking changes. * Please, use wp_style_engine_get_styles() instead. * * @access private * @since 6.1.0 * @since 6.3.0 Added support for text-columns. * @since 6.4.0 Added support for background.backgroundImage. * @since 6.5.0 Added support for background.backgroundPosition, * background.backgroundRepeat and dimensions.aspectRatio. * @since 6.7.0 Added support for typography.writingMode. * @since 7.0.0 Added support for typography.textIndent. / #[AllowDynamicProperties] final class WP_Style_Engine { /* * Style definitions that contain the instructions to parse/output valid Gutenberg styles from a block's attributes. * * For every style definition, the following properties are valid: * * - classnames => (array) an array of classnames to be returned for block styles. The key is a classname or pattern. * A value of `true` means the classname should be applied always. Otherwise, a valid CSS property (string) * to match the incoming value, e.g., "color" to match var:preset\|color\|somePresetSlug. * - css_vars => (array) an array of key value pairs used to generate CSS var values. * The key should be the CSS property name that matches the second element of the preset string value, * i.e., "color" in var:preset\|color\|somePresetSlug. The value is a CSS var pattern (e.g. `--wp--preset--color--$slug`), * whose `$slug` fragment will be replaced with the preset slug, which is the third element of the preset string value, * i.e., `somePresetSlug` in var:preset\|color\|somePresetSlug. * - property_keys => (array) array of keys whose values represent a valid CSS property, e.g., "margin" or "border". * - path => (array) a path that accesses the corresponding style value in the block style object. * - value_func => (string) the name of a function to generate a CSS definition array for a particular style object.
