Icons Size Won't Change in Advanced CSS Code

Does anyone know how to fix these 2 issues for me?, really need an answer please. Thanks.

Your Additional JS is working, but there’s no sign of your Additional CSS. Try to pinpoint the cause by making sure your site’s cache(s) are cleared, temporarily deactivating other plugins and/or switching themes.

CSS code for your counters, too:

.a2a_floating_style .a2a_svg {
    background-size: 48px;
    height: 48px;
    width: 48px;
}
.a2a_floating_style .a2a_count {
    width: 48px !important;
}

That code worked! Thank you so much… one last question… is there a way to make the icons move down as I scroll up and down the page?

You can make that happen with some custom JavaScript work. But generally I’d advise against doing things on scroll because it can cripple page performance on lesser devices (unless the function is properly throttled or debounced).

I see, thanks again!
