Watermark for all pages

[ays-code]

Hi.

I'm putting a watermark in all pages on the pdf but I can't do it successfully. I've tried on the header and footer but there are some issues and it's not showing correctly because the image is large.

The only way is to put this css on the pageContent section but the image is only showing on the first page.

    #pageContent:after {
      content: "";
      display: block;
      position:fixed;
      bottom:0;
      right:0;
      top:0;
      left:0;
      width: 100%;
      opacity: 0.5;
      background-image: url("file:///path/image.png");
      background-repeat: no-repeat;
      background-position: center top;
      background-size: contain;
    }

Any ideas to show it on the other pages?

Thanks. Edwin.
