    Markdown Features

    Supports for CSS Style

    Use HTML comments <!--rehype:xxx--> to let Markdown support style customization.

    ## Title
    <!--rehype:style=display: flex; height: 230px; align-items: center; justify-content: center; font-size: 38px;-->
    Markdown Supports **Style**<!--rehype:style=color: red;-->

    Support for GFM footnotes

    Here is a simple footnote[^1]. With some additional text after it.
    [^1]: My reference.

    Support dark-mode/night-mode

    By default, the dark-mode is automatically switched according to the system. If you need to switch manually, just set the data-color-mode="dark" parameter for body.

    <html data-color-mode="dark">
    document.documentElement.setAttribute('data-color-mode', 'dark')
    document.documentElement.setAttribute('data-color-mode', 'light')

    Inherit custom color variables by adding .wmde-markdown-var selector.

    const Demo = () => {
      return (
          <div className="wmde-markdown-var"> </div>
          <MarkdownPreview source="Hello World!" />


    Runs the project in development mode.

    # Step 1, run first,
    # listen to the component compile and output the .js file
    # listen for compilation output type .d.ts file
    # listen to the component compile and output the .css file
    npm run watch
    # Step 2, development mode, listen to compile preview website instance
    npm start

    Builds the app for production to the build folder.

    npm run build

    The build is minified and the filenames include the hashes. Your app is ready to be deployed!
