Building Interactive Blog Posts with MDX

By: O Wolfson

In the digital age, the way we consume content is rapidly evolving. Gone are the days when blog posts were mere static texts with images. Today, interactivity is key to engaging readers and providing an immersive experience. Enter MDX, a powerful syntax that blends Markdown with React components, allowing you to create highly interactive and dynamic blog posts. In this post, we'll explore how you can use MDX to transform your blog into an interactive experience.

What Makes MDX Stand Out for Interactivity?

MDX breaks the barrier between content and code. With MDX, you can seamlessly integrate interactive JavaScript and React components within your blog posts. This means you can include elements like interactive graphs, live code editors, or even games directly in your posts.

Getting Started: Setting Up MDX

Before diving into creating interactive content, ensure you have a blog set up with MDX. Most static site generators like Next.js or Gatsby support MDX with minimal configuration.

Example: Adding an Interactive Quiz to Your Blog Post

Let's create a simple interactive quiz in your blog post.

  1. Create a Quiz Component:
    • First, build a React component for your quiz. This component can handle state, user interactions, and display results.
"use client";
import React, { useState } from "react";
import styled, { keyframes } from "styled-components";
import Confetti from "react-confetti";
import { Button } from "@/components/ui/button";

interface QuizProps {
  question: string;
  options: string[];
  correctAnswer: string;

// Keyframes for dancing ants animation
const dancingAnts = keyframes`
  to {
    background-position: 100%;

// Styled component for Quiz with dancing ants border
const QuizContainer = styled.div`
  border: 2px dashed black;
  background: linear-gradient(white, white) padding-box, repeating-linear-gradient(
        black 0,
        black 25%,
        white 0,
        white 50%
      ) 0 / 0.6em 0.6em;
  animation: ${dancingAnts} 1s linear infinite;
  border-radius: 0.8rem;
  padding-top: 0;
  padding-right: 1.5rem;
  padding-bottom: 1.5rem;
  padding-left: 1.5rem;
  position: relative; // Needed for confetti

const Quiz: React.FC<QuizProps> = ({ question, options, correctAnswer }) => {
  const [userAnswer, setUserAnswer] = useState < string > "";
  const [result, setResult] = useState < string > "";
  const [showConfetti, setShowConfetti] = useState < boolean > false;

  const handleOptionClick = (option: string) => {
    setResult(""); // Reset the result when a new option is selected
    setShowConfetti(false); // Hide confetti when a new option is selected

  const checkAnswer = () => {
    if (userAnswer === correctAnswer) {
      setShowConfetti(true); // Show confetti for correct answer
    } else {
      setResult("Try again!");

  return (
    <QuizContainer className="overflow-hidden">
      {showConfetti && (
        <Confetti width={window.innerWidth} height={window.innerHeight} />
      <div className="flex flex-col gap-2 items-start mb-3">
        { => (
            className={`py-1 px-3 ${userAnswer === option ? "font-bold" : ""}`}
            onClick={() => handleOptionClick(option)}
      <div className="mb-3">
        <Button onClick={checkAnswer}>Submit</Button>
      <div>{result && <div className="text-2xl font-bold">{result}</div>}</div>

export default Quiz;
  1. Embed the Quiz in Your MDX:
    • In your MDX file, import the Quiz component and add it where you want the quiz to appear.
import Quiz from '../components/Quiz'

Other Interactive Elements You Can Add

  • Live Code Editor: Integrate a live code editor for readers to try out code snippets.
  • Interactive Graphs: Display data in a more engaging way using interactive graphs or charts.
  • Feedback Forms: Embed forms directly into your posts for instant reader feedback.
  • Animations: Use React libraries to add animations that react to user interactions.

Best Practices for Interactive MDX Content

  1. Keep It Relevant: Ensure that the interactive elements are relevant to the content and add value to the reader's experience.
  2. Performance Matters: Interactive components can be heavy, so be mindful of the performance impacts on your site.
  3. Accessibility is Key: Make sure your interactive elements are accessible to all users, including those with disabilities.


MDX opens up a new realm of possibilities for blog content, blending narrative with interactivity. By leveraging the power of MDX, you can create blog posts that are not just informative but also engaging and interactive. As you experiment with different components and interactivities, you’ll find new ways to captivate your audience and enhance their reading experience. Happy blogging!
