Pin to screen on Mobile device

Is it possible to pin an element to screen on a mobile device? I would like to create a floating button.

You can’t do it in the classic editor, but I believe you can in editorX (but not sure, you’ll have to try).

As Giri said you can do it with EditorX.
(In the classic editor, you’ll have to create your own element using custom element and set it css style to be position:fixed; But It’s much easier to do it with EditorX as no code is needed).

Do you have instruction or documentation on how to accomplish this in editor x?
