Hello to all! I need a critical look at my project. Like it or not leave the comments.
The code in the codepen is messy though.
Thank you very much for your feedback @JohnnyBizzel! Maybe you can give a link to the materials about the correct structure of the code. I would be grateful for the help.
On codepen you don’t need head tags or html or body.
Use settings to add external scripts and libraries.
You can also “tidy” the code. (see the carat on the top right of the window)
