Dear @luca123,

In the article below you can find an example that includes a background color change, feel free to adapt it to your needs.

Anyway, as attached files I share with you a single script using JS to change a div color inside the html canvas, please keep in mind that the html canvas is intended for users with knowledge of CSS, HTML and JS, if you are not familiar with these concepts we advise you to learn about them before of trying to use the widget.

All the best,
Maria C.
