How can I find a documentation about custom elements? Do you guys have something about it?
Here’s an article to help you get started: “About Custom Elements”
I have read all of them and created an example from scratch right now in Editor X but I want a real documentation source like W3 or MDN

Here’s the API documentation for Custom Element: https://www.wix.com/velo/reference/$w/customelement
And here’s an example built using a Custom Element: https://www.wix.com/velo/example/alert-messages
We don’t have a lot of other documentation about it. But if you post a specific question, many of our Velo Masters are experienced with Custom Elements and should be able to assist.
