On the left is the Markdown document editing area, and on the right is the preview after styling and the block editing area.
This block has the function of editing Markdown documents using SimpleMDE, and by parsing Markdown documents using marked, it can assign specific blocks to the converted HTML elements.
This function allows users to customize Markdown documents using the styling functions of the corresponding blocks, allowing for a wide range of styling.
The following are the blocks that are applied when Markdown documents are parsed into HTML elements.
The H element is also generated as a table of contents, and has the function of displaying nested items according to level.
This plugin does not require any external resources (all scripts and styles are included locally)
PHP class management is now done using Composer.
