Give page an image border

Hi, I am trying to place a repeating image border on the #page element. So far I am able to give it a color border, but I haven't been able to make the image display. The ideal would be for it to be just on the left side, second choice on both the left and the right. I'd have to see it but suspect that all four sides would be too much. When I look at the selectors I have been unable to find code addressing what I am trying to do. This is what I have so far:

#page {
	border-image-source: url("http://dynamictherapies.net/wp-content/uploads/2019/02/vineBorder.png") ; 
  border-image-repeat: repeat; 
}	

The site is here Can you suggest a solution?
