Core Media Text – PRC Platform

PRC's minimal override of the WordPress core/media-text block.

Block Namespace

core/media-text (no separate PRC block.json — PHP-only override)

What PRC Customizes

Defaults the align attribute to "center" and adds "center" to allowed alignments
Adds inline styles for margin, content border, quote/cite formatting within the media-text block

Supports Modifications

Support	Change
`align`	Default changed to `"center"`; allowed values: `wide`, `full`, `center`

Applied via block_type_metadata filter in default_align_center.

Additional Attributes

None beyond the modified align default.

Available Styles

None.

Style Overrides

Inline styles applied via wp_add_inline_style:

Block margin — margin-block-end: 1.5em
Content border — border-left: 3px solid white on .wp-block-media-text__content at min-width: 768px
Blockquote — zero padding and margin on nested .wp-block-quote
Citation — cite styled as a right-aligned block at font-size: 15px, width: calc(100% + 8%), with a ::before pseudo-element displaying an underscore character positioned above
Color inheritance — .has-text-color variants inherit color on quote and citation elements

Editor Enhancements

None. No editor script.

Frontend Interactivity

None. No view script.

PHP Rendering

File: class-core-media-text.php

default_align_center (block_type_metadata filter) — sets align attribute default to "center" and updates supports.align to include center
register_style (enqueue_block_assets hook) — adds inline CSS to wp-block-library (in admin) or wp-block-media-text (on frontend)

No render filter modifications to block content.
