Help! I somehow managed to delete the Add footer using Add section option. Thanks in advance :-)

My url is https://carlsonphoto.se

My Custom CSS looks like this:

.header-nav-folder-item a {
    padding-top: 10px !important;
}
.header-nav-folder-item--active a {
    color: darkturquoise !important;
}

.header-menu-nav-item a {
    line-height: 1.5em;
}

/* Masonry one item on mobile */
@media screen and (max-width:767px) {
    .gallery-masonry-wrapper.gallery-masonry-list--ready {
    height: auto !important;
}
figure.gallery-masonry-item {
    position: relative !important;
    width: 100% !important;
    transform: unset !important;
}
.gallery-masonry-item-wrapper {
    height: auto !important;
}
.gallery-masonry .gallery-masonry-item[data-loaded] img {
    width: 100% !important;
}
.gallery-masonry {
    padding-left: 20px !important;
    padding-right: 20px !important;
}

Code injection:

HEADER: 

header a {
background-image: none !important;
}

FOOTER:

empty

The code injection 

Code injection:

FOOTER:

empty

is not doing anything. You need to rebuild the footer. Add the section at the bottom and any blocks that were in that section.
