MDX Components

One of the most powerful features of MDX is the ability to use React components directly in your markdown.

1
export const Highlight = ({ children, color }) => (
2
  <span
3
    style={{
4
      backgroundColor: color,
5
      borderRadius: "2px",
6
      color: "#fff",
7
      padding: "0.2rem",
8
    }}
9
  >
10
    {children}
11
  </span>
12
);
13

14
<Highlight color="#25c2a0">This is highlighted!</Highlight>;

Custom Callouts

You can create custom components for callouts:

1
<div className="callout callout-info">
2
  <strong>Info:</strong> This is an informational message.
3
</div>
4

5
<div className="callout callout-warning">
6
  <strong>Warning:</strong> This is a warning message.
7
</div>
8

9
<div className="callout callout-success">
10
  <strong>Success:</strong> This is a success message.
11
</div>
