Golden Healing Academy
Practice coding lab
Write HTML, CSS and JavaScript and see the result immediately. No account needed, nothing is uploaded, and your work saves in this browser so you can come back to it.
This is a free playground — there is no marking and no time limit. Try changing the heading, then the button colour, then what the JavaScript does when the button is clicked.
Your code should
- Render your own heading and paragraph text
- Restyle the button with your own colours
- Make the button do something different when clicked
