Home page margin issue

Site URL: https://www.elevateptr.com/

Hi - how do I remove the site margin from the first section on my home page? I'm trying to get the image to bleed off the page.  code below

// Background photo on website //

div#block-91b1941b9ee6e3e75d6c {
    padding-left: 0px;
      padding-right: 0px;
      padding-bottom: 45px;
  }

@media only screen and (max-width: 767px){
  div#block-91b1941b9ee6e3e75d6c{
  padding-top: 0px !important;    
  padding-left: 0px !important;
  padding-right: 0px !important;
  width: 110%;
  left: -5%;
  }
}

Add to Home > Design > Custom CSS

.homepage #page section:first-child .content-wrapper {
    max-width: 100%;
    padding: 0 !important;
}
