In this third Web Components tutorial, we take our custom button (my-button) to the next level by making it reactive — it now observes attributes and responds dynamically when the disabled state changes.
Here’s what you’ll learn in this video:
🎯 How to use the observedAttributes getter to monitor changes
⚡ How attributeChangedCallback() works and when it fires
🔒 How to implement and style a disabled state for your component
🧩 How to programmatically toggle attributes using JavaScript
By the end, you’ll understand how to make your components respond to attribute changes in real-time — an essential step toward truly interactive, framework-free UI elements.
🧠 Concepts covered:
observedAttributes and attributeChangedCallback()
Managing state through attributes
Styling disabled states
DOM scripting for component interactivity
