CSS Sandbox
A toy.
A teacher.
A live demo.
A quick reference.
A web application.
A single HTML page.
The CSS Sandbox can be described by all these sentences.
It’s a simple and quick web toy that lets you explore CSS in real time. Just click and see the effect instantly, no Reload needed. It’s fast and funny!
Once you’re satisfied with the style of the Sandbox, roll your mouse over the handy CODE button. A panel will pop, showing all the necessary CSS code to apply that formatting to your own site.
