20 Awe-Inspiring Codepen Examples You Can Learn From

CodePen.io is an online code editor that allows you to develop in an open-source environment. You create 'pens' which display a live-preview as you code which is great for testing out bugs, collaborating and discovering the latest design patterns. CodePen supports a great selection of languages, frameworks and libraries which you can quickly spin up into a pen to get coding on straight away.

As an avid user and supporter of CodePen, I have stumbled across many creative and inspiring pens and thanks to 'editor view' I have been able to learn from the code used to build them. Not only has this helped me grow as a JavaScript Developer, it has introduced me to different programming patterns and techniques I would never have been exposed to before.

Listed below are 20 awe-inspiring CodePen examples you can learn from. Make sure you take the time to read over the code and compliment the user by hearting or leaving a comment on the pen.

Please note, it's worth taking the time to check the following pens out on your desktop browser. Some are JavaScript heavy or not built for mobile so your overall experience will be better.
