How to remove or make transparent the canvas background for one page.

I'm trying to remove the lighter white canvas on mysite, managed to remove the background image and toolbar, but haven't been able to remove the transparent canvas.  Any way to remove this or make it fully transparent?

Example: https://www.cattrigger.com/game-date-time

The theme is also "Avenue".

Sorry, I don't understand.  Would you be able to clarify what you mean by sending an image here?  

I sent an example link.  I want to get rid of the light white background canvas in it just for that one specific page.

Add this code to Design > Custom CSS
 

div#canvas {
    background: transparent !important;
}

Also, I see a code appear in top of site

Is there a way to put this only in this one page, as opposed to having it applied to every page I have?
