I have always been a supporter of CodePen ever since I found the website. It is an online HTML/CSS/JS code editor where you can build ideas and test them in real-time. Developers can also share their pens with others all around the world! It is a great web application which allows frontend developers to practice their skills from any computer with Internet access.
I’ve gone through the latest pens and gathered 30 of the best code samples. Projects which are free to duplicate will have an open source license on the codes. Ideally these can save you time and stress when attempting to build more convoluted interfaces. Granted you may not find a use for all of these concepts. But it is worth skimming the collection just to see what is out there and what is possible when building with CodePen’s IDE.
