Zero setup, full-featured front end web development environment, right here in your web browser.
Web Design 101. You have a homepage and a contact page. Your
index.html links to
<a href="contact.html">anchor link</a>.
That works exactly as you think it would in the CodePen Project Editor.
Everything works exactly as you would expect in developing a website
with a local file system and simple web server. Relative file paths to
your images? No problem.
@import in your CSS? Do
it. Ajax requests? Sure thing. Nested folders? Got ’em.
Have an existing project elsewhere? Maybe a git repo you cloned locally and want to play with? You can drag the files into the Project Editor and get working right away.
Don’t buy expensive software that you have to install on every computer and keep upgraded by hand. You can get to teaching instantly with the CodePen Project Editor, in a ready-to-go environment that is just like a real world web development environment.
Beyond that, starter templates help jumpstart a session past even more setup and right into the important parts.
Like to write your CSS with Sass? We got you. Just name the file, for example, with the file extension `.scss` and we’ll understand and process that file for you. Included partials and all. We’ve got all the major ones covered:
You’ll be able to deploy a CodePen Project to a static website. It’s a one click process for PRO users!
The Project Editor then becomes your development version. You’ll be able to make changes and save your project without affecting the deployed version.
