Customized Bottom Footer not visible

Site URL: http://www.qualitycupofcoffee.com/french

Hello,

I tried to customize the top of my bottom footer. I used this technique to customize my pages on my website. However, this time, I cannot see the customized look unless I am "editing" the bottom footer. When I am done editing, the image does not appear ... Ideally I would want just the small "biscuit" like shape to be just on top of my bottom footer.

Any ideas ?
Thanks

#footerBlocksBottom { background-color: #FFA899;}
#footerBlocksBottom  {
background: #FFA899;
overflow: visible !important;

 &:before {
    content: '';
    width: 100%;
    height: 150px;
    top: 0;
    left: 0;
    background-image: url(https://static1.squarespace.com/static/5a5e3c50a9db09fc9c1233de/t/601184b8ba655709b83777c8/1611760824081/mini+footer.png);
    background-size: contain;
    background-repeat: repeat-x;
    background-position: bottom;
    margin-top: -100px;
    position: absolute;
    pointer-events: none;

    @media screen and (max-width: 800px) {
      background-size: 200% 50%;
    }
  }
}

Keep above code & add this to Design > Custom CSS

div#footerBlocksBottom {
    position: relative;
}
