How do I make my footer transparent

Hey guys I need some help.

I've managed to make my footer sticky by using this code:

//sticky footer
#footer-sections {
position: fixed!important;
width: 100%!important;

bottom: 0!important;
z-index: 99!important
}

I,ve disabled the code until I get the solution, but if needed I can enable it

The problem is that it has a black background in this case, but I want it to be transparent as the header, so you can see the content passing through the footer.  Any solutions??

Use this CSS code

body {
    position: relative;
}
footer#footer-sections {
    position: absolute;
    bottom: 0;
    left: 0;
    z-index: 999;
    width: 100%;
}
footer.sections section, footer.sections .section-background, footer.sections .section-border {
    background: transparent !important;
}
