Social code playground for building and sharing front-end experiments

About CodePen

CodePen is an online code editor and community for front-end development. You build 'Pens' with HTML, CSS and JavaScript side by side and watch results update live, which makes it ideal for prototyping components, testing ideas and learning from millions of shared examples. Preprocessors, external libraries and frameworks can be added with a click, and Pens can be embedded into articles and documentation. Collections, challenges and a vibrant community feed make discovery part of the experience. It serves front-end developers, designers, students and educators. The free plan covers unlimited public Pens; PRO adds private Pens, asset hosting and collaboration modes.
