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>
<div className="wmde-markdown-var"> </div>
<MarkdownPreview source="Hello World!" />
</div>
)
}
Set the light
theme.
<MarkdownPreview
source="Hello World!"
warpperElement={{
+ "data-color-mode": "light"
}}
/>
