This plugin extends the block editor by adding margin controls to content blocks, giving site builders and designers direct control over vertical spacing. It is particularly useful for users who need to fine-tune the layout and visual hierarchy of their pages without writing custom CSS.

• Margin Controls: Adds a toolbar control to set a top margin for blocks, with predefined options like small, medium, and large.
• CSS Classes: Applies a corresponding CSS class (e.g., has-medium-margin-top) to the block when a margin option is selected, ensuring consistent styling.
• Developer Filters: Provides JavaScript and PHP filters (blockMargin.excludedBlocks, blockMargin.controls) to customize which blocks have controls and what margin options are available.
• Server-Side Support: Includes server-side filters (block_margin_excluded_blocks, block_margin_options) to ensure margin attribute registration and options are synchronized for blocks rendered on the server.
