Question for adding scroll up button

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

.scrollup {
    width: 48px;
    height: 48px;
    opacity: 0.8;
    position: fixed!important;
    bottom: 20px;
    right: 40px;
	z-index: 1;
    display: none;
    text-indent: -9999px;
}

I used the code like this, and insert the block into the footer.

But the problem is, I want the scroll up button float and fixed on the screen, but if I put the block in the footer, it just stays in the area of the footer.

I tried adding a block outside of the future and those codes work well. However, I don't want to insert new block in every page. Does anyone know how to deal with the blocks in the footer?

BTW, I've used these codes for a long time, and everything looks good when I first implemented it. Did the Squarespace upgraded these days?

So instead place it in footer section, try adding it into Code Injection Footer instead
