Mkdocs Mask Plugin

A MkDocs plugin that adds a custom !mask[...] syntax to hide text behind a black box until hovered.

Install

pip install mkdocs-mask-plugin

Usage

1. Enable the Plugin

In your mkdocs.yml configuration file, add the plugin:

plugins:
  - mask

2. Use the !mask[...] Syntax in Markdown

In any Markdown (.md) file, wrap the sensitive or hidden text using the !mask[...] syntax:

Do not reveal this unless you're ready: !mask[This is a hidden message].

This will render as a black box that hides the text until the user hovers over it.

---

3. Resulting Behavior

The masked content will appear as a blacked-out block like this:

Do not reveal this unless you're ready: ██████████████████

When the user hovers their mouse over it, the black box fades away and the original text is revealed with a smooth transition.
