If you don’t have that artistic sense, CodePen can also be useful for simple things like: creating a first simple version of an idea, storing code to use as an iframe on another site, testing some library or framework (CodePen allows the use of libraries and frameworks through CDN) and more what your imagination allows.
Soloearn is a platform that I use to learn something new or simply remember concepts that I forgot over time. This platform has several courses that are divided into theoretical content in text and practical content in the form of exercises.
In addition, Sololearn has a forum where you can interact with other users and a “Code Playground” that allows you to unleash your imagination and easily put into practice the new knowledge obtained.
