CodePen
CodePen is a social development environment for front-end designers and developers. 👋 It’s the best place to build and deploy a website, show off your work, build test cases, and find inspiration. We call them Pens. Write HTML, CSS, and JavaScript and get a real-time preview. You can use CodePen to: • Show off the amazing things you build. • Learn new things by tinkering. • Build reduced test cases to report bugs and get help on tricky problems. • Try out new technologies for the first time. • Build components to later use elsewhere. • The possibilities are endless. Everything you do is saved on CodePen, so the more you use it the more useful it becomes.
