playground integration

Hey, @EmmaDawsonDev and team great work 👏
I highly appreciate the work!!! I am looking forward to being part of this amazing journey.

### Feature request

**Present**
The initiative taken to explain each pattern with code examples and demos is amazing. Currently, the code, demo, and styling are isolated. What I meant by isolation is, let's look at the below page [breadcrumbs](https://accessibleweb.dev/breadcrumbs#).

Here we start with an introduction, show a demo then give code and the styling.

**Feature**

a playground where users can interact with code and look at live demos. For example in [react.dev ](https://react.dev/learn/your-first-component) they give code editor to live demo.


can I get the chance to work on this feature ?
