Make page transparent to show CSS background image

Hello,

I'm trying to get a fixed, full-width image onto my landing page. I added the CSS for the background image, but I can't make the page section's background transparent to show the image. Any help would be greatly appreciated!

This is the code I currently have injected in the page header:

<style>
  .header, #footer-sections {display:none!important}
/* homepage background */
  #page .page-section {
background: transparent!important
}

#page .page-section .section-background {
background: transparent !important;
}
  
body::before {
background-image:url(https://static1.squarespace.com/static/61cf79abb29d4211ca17caac/t/6419e5b80345d51569c4466b/1679418808939/zhijian-dai-LeJsiKbPElY-unsplash.jpg);
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  content: '';
  height: 100%;
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;

  }

</style>

Change this line

#page .page-section .section-background {
background: transparent !important;
}

to this

#page .page-section .section-background, .section-border, .section-divider {
background: transparent !important;
}
