Website on Internet Explorer

Hi there,

I am using the Virtue theme by Kadence. My website is fine on other browsers, but it seems to be wonky on Internet explorer. Is there any way to add some quick .css to advanced styling tab to fix this? Thanks in advance.

1) The top bar social icons are centered when they should be on the top right.

2) The quantity number is not in the middle.
