I can't outline my text with custom code

This is my first time using custom code. It is probably an easy fix.

Can anybody check why the custom code doesn’t work?

Thx!

Here is my read-only link:

It seems to work if you publish… since you added the code in the page’s custom code, you can’t see the result in the designer / editor.
If you want to see the result in the designer / editor, you need to add this custom code to an embed element inside a page.
