Looking to Change my Blog Navigation Buttons

I want to change the blog navigation buttons on my Squarespace blog. I would like the right arrow to go to the next post, and the left arrow to go to the previous post (which is opposite from the way that Squarespace automatically has it set up). 

You can add this code to Website Tools (under Not Linked/Hidden) > Custom CSS

section#itemPagination {
    display: flex;
    flex-direction: row-reverse;
    justify-content: space-between !important;
}
section#itemPagination>a:first-child {
    margin-right: 0 !important;
}
section#itemPagination>a:nth-child(2) {
    margin-left: 0 !important;
}
section#itemPagination>a {
    display: flex;
    flex-direction: row-reverse;
}
section#itemPagination svg {
    transform: rotate(180deg);
}
