When working in the editor, some experiences require that custom logic be run when certain events occur, since this logic depends on specific use cases, the editor has a script property where a custom javascript can be entered. This script will be executed during the run time (i.e., in the view mode)

Here's an example that uses custom javascript:

{% content-ref url="/pages/kRdiXky3wjGF3bhyBGxP" %}
[Adding Background Music & Persistent Logo](/guidelines-compatibility/guidelines/workflows/adding-background-music-and-persistent-logo.md)
{% endcontent-ref %}
