Yes, this is what dabblet is all about – an interactive CSS playground. I was looking for a online tool where I could easily put in HTML source code, and play around with it. Due to the fact I’m more in backend development I’m not used in daily frontend development. My goal: Copy generated HTML-source code into the browser (or where ever) to get instantly a result.
And as usual I stumbled upon dabblet the other day. So I tested it, and considered it to be accurate and fitting my needs. The project is also hosted on GitHub: https://github.com/LeaVerou/dabblet
Very enjoyable tool – give it a try.
