Continous image for main page and footer

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

How do I make the background image for my site stretch to my footer? I want the image to be used as a huge continous image for the site. This is works for the header but not the footer.

Add to Design > Custom CSS

.section-background, .page-section {
    background: transparent !important;
}
body {
   background-image: url(https://cdn.pixabay.com/photo/2021/01/07/22/15/dandelion-5898546__340.jpg);
   background-size: cover;
   background-repeat: no-repeat;
   background-position: center center;
   background-color: transparent !important;
}
