I added a sticky header but it overlaps store

how can I fix this? I use debut theme

www.petbenefit.net

hii, @aimeemorash7
Paste this code on top of the theme.scss file.

@media only screen and (max-width: 749px) {
main#MainContent {
    margin-top: 100px !important;
}
}
@media only screen and (min-width: 992px) {
main#MainContent {
    margin-top: 145px !important;
}
}

Thank You.

thank you so much!
