Hide Title Using JavaScript in Custom HTML Prompt Action

I've created a clock within the Custom HTML Prompt action and I wondered if it's possible to hide the prompt's title bar through JavaScript?

The use case would be to position the prompt on my screen and use a click event show/hide the title.

You can uncheck the Title option found in Custom HTML Prompt action menu

But there is no way you can restore the title by just clicking on it, and you will need to use some mouse event to accomplish the positioning.

Thanks for the reply, seems the original idea is too advanced for the moment. I ended up hiding the title and then using the arrow keys to position the window.
