原文外掛簡介

Block Style Modifiers is a simple WordPress plugin that allows you to add multiple block styles to Gutenberg blocks.
Style Modifiers are additive CSS classes that:

Can be applied in addition to a Block Style
Can be selected multiple at the same time
Support both checkbox (non-exclusive) and radio (exclusive) behavior per category
Are predefined and documented by themes or plugins
Preserve class order, allowing advanced CSS control

Category Behavior
Style modifiers are organized into categories with two behaviors:

Non-exclusive categories (checkbox): Multiple modifiers can be selected simultaneously (default: exclusive: false)
Exclusive categories (radio): Only one modifier from the category can be selected at a time (exclusive: true)

Structured Category Object
Categories must be defined as objects with:

slug – Language-independent identifier for grouping (required)
label – Translatable UI label (required)
description – Optional category description
exclusive – Boolean flag for radio behavior (default: false)

Features

Register multiple style modifiers for any block type
Apply multiple style modifiers to a single block
Global style modifiers that apply to all blocks
Inline CSS support for easy styling of modifiers
Structured category objects with exclusive/non-exclusive behavior
Theme-independent default modifiers via Block Style Modifier Pack

Default Modifiers
Block Style Modifiers includes theme-independent default modifiers that work with any WordPress theme:
Philosophy:
* Enhance behavior, not visual design
* No borders, shadows, spacing, or color palettes
* Work with any theme without conflicts
* Atomic and performant
* Respect prefers-reduced-motion
Available Categories:
Animations (Exclusive) – Entrance animations for wrapper blocks
* Fade In – Smooth fade entrance
* Slide Up – Slide from bottom
* Slide Down – Slide from top
* Slide Left – Slide from right
* Slide Right – Slide from left
* Scale In – Scale up animation
* Rotate In – Rotate with fade
* Flip In X – 3D flip animation
Applied to: Group, Row, Stack, Grid, Column, Columns (wrapper blocks only)
Animation Delay (Exclusive) – Control animation timing
* Fast (0.2s)
* Normal (0.4s)
* Slow (0.8s)
Hover Effects (Exclusive) – Transform-based hover interactions
* Zoom In on Hover
* Subtle Rotate on Hover
* Bounce on Hover
* Shake on Hover
* Brighten on Hover
* Darken on Hover
* Grayscale to Color on Hover (Image/Cover only)
* Blur to Focus on Hover (Image/Cover only)
Applied to: Image, Cover, Media & Text (content blocks only)
Text Effects (Exclusive) – Micro-interactions for text
* Underline Reveal on Hover
* Soft Text Fade on Hover
Applied to: Paragraph, Heading (text blocks only)
All default modifiers respect accessibility preferences and are disabled when prefers-reduced-motion is set.
Architecture Note: Animations are only available for wrapper blocks (Group, Row, Stack, etc.) while Hover Effects are for content blocks (Image, Cover, Media & Text). This separation prevents CSS property conflicts and ensures all modifiers work seamlessly together.
You can easily extend or override these defaults by registering your own style modifiers in your theme or custom plugin.
Usage

Define your style modifiers using the block_style_modifiers_register_style function via your theme’s functions.php file or a custom plugin.
Select style modifiers in the block editor sidebar under “Block Style Modifiers”.
Style modifiers will be applied as additional CSS classes to the block’s wrapper element.
It is possible that reordering of classes may affect CSS specificity and styling.

Note: There is available an experimental plugin includes blocks style modifiers: Block Style Modifier Pack plugin to function.
Registering a Block Style Modifier
You can easily register your own style modifiers in your theme or custom plugin.
Here are some examples of how to register style modifiers with different category behaviors:
Exclusive Category (Radio Behavior)
block_style_modifiers_register_style( [ 'core/image', 'core/cover' ], [
'name' => 'zoom-on-hover',
'label' => __( 'Zoom on Hover', 'my-theme' ),
'class' => 'bsm-zoom-on-hover',
'description' => __( 'Zoom into image on hover', 'my-theme' ),
'category' => [
'slug' => 'hover-effects',
'label' => __( 'Hover Effects', 'my-theme' ),
'description' => __( 'Transform-based hover interactions', 'my-theme' ),
'exclusive' => true,
],
] );

Non-Exclusive Category (Checkbox Behavior)
block_style_modifiers_register_style( '*', [
'name' => 'hide-sm',
'label' => __( 'Hide on Small Screens', 'my-theme' ),
'class' => 'bsm-hide-sm',
'category' => [
'slug' => 'responsive',
'label' => __( 'Responsive', 'my-theme' ),
'description' => __( 'Responsive visibility controls', 'my-theme' ),
'exclusive' => false,
],
] );

That’s it! You can now select multiple style modifiers for your blocks in the Block Editor.
Example Result in Markup
class="wp-block-cover has-custom-content-position is-position-bottom-left bsm-zoom-hover bsm-fade-in bsm-delay-normal"

It is important to note that the order of classes may affect CSS specificity and styling. You can easily reorder your modifiers with drag/drop functionality in the Block Editor.
