Mermaid Block Placement Guide
- Open a post or page in the WordPress block editor.
- Click + Add block.
- Search for Mermaid or PlusMagi Blocks + Mermaid.
- Insert the Mermaid block.
- Paste Mermaid syntax (for example
graph TD\nA-->B). - Confirm the live preview in editor.
- Publish and verify diagram rendering on frontend.
Tips:
- Use one Mermaid diagram per block for cleaner editing.
- For long technical articles, split diagrams into multiple Mermaid blocks.
- If preview does not render, check Mermaid syntax first (missing arrows, brackets, keywords).
SVG Block Guide
- Open the block inserter and search for SVG or PlusMagi.
- Insert the PlusMagi – SVG block.
- Paste markup that starts with an
<svg>element. - Confirm the preview in the editor.
- Publish the post or page.
The block renders responsive inline SVG. Scripts, event handlers, and unsafe inline styles are removed before frontend output.
PlantUML Block Guide
- Open the block inserter and search for PlantUML or PlusMagi.
- Insert the PlusMagi – PlantUML block.
- Write markup starting with
@startuml(or another PlantUML@starttag). - Choose SVG or PNG as the output format.
- Confirm the preview in the editor, then publish the post or page.
The block renders the diagram by requesting an image from the public PlantUML server; no local Java/Graphviz installation is required.
Sticky Notes Block Guide
- Open the block inserter and search for Sticky Notes or PlusMagi.
- Insert the PlusMagi – Sticky Notes block.
- Write the note and choose one of six colors in the block settings.
- Publish the post or page.
The block publishes an accessible <aside role="note"> element in a responsive 2 x 3 inch layout. It supports bold, italic, links, text color, font size, line height, font family, weight, style, decoration, and letter case through Gutenberg controls.
Description List Guide
- Open the block inserter and search for Description List or PlusMagi.
- Insert the PlusMagi – Description List block.
- Enter a term and its description.
- Use the block controls to add or remove items.
- Publish the post or page.
Example output:
<dl>
<dt>WordPress</dt>
<dd>A content management system for building websites.</dd>
<dt>Gutenberg</dt>
<dd>The block editor included with WordPress.</dd>
</dl>
The block publishes semantic <dl>, <dt>, and <dd> markup for accessible term-and-description content.
Table Style Guide
- Insert or select a standard Gutenberg Table block.
- Open the block settings sidebar and expand Table Design.
- Choose one of the 107 styles.
- Optionally enable Banded Columns.
- Choose None at any time to remove the design without changing table content.
Table Styles extend the native Gutenberg Table block. They do not add a heading to published content.
