Making Your Blog Interactive

Static blogs don’t have to be boring! With MDX and Astro components, you can create rich, interactive experiences.

Using Components in MDX

The best way to learn is by doing. Start experimenting with components today!

MDX allows you to use components directly in your markdown:

This is a note component that highlights important information.

Sidenotes for Additional Context

You can add sidenotes that appear in the margin, providing additional information without cluttering the main text.

Mathematical Expressions

You can also include mathematical expressions using KaTeX:

E=mc2E = mc^2

Inline math works too: a2+b2=c2a^2 + b^2 = c^2

Code Examples

// Interactive code blocks with syntax highlighting
function greet(name) {
  return `Hello, ${name}!`;
}

console.log(greet('World'));

Conclusion

The possibilities are endless when you combine the power of MDX with Astro’s component system!
