Resizing of buttons

I needed to resize the buttons, but found they were hardcoded to 45px square. I refactored the CSS to use percentages, and thought I’d post the code here for anyone else who wishes to use it. No you just need to change lines 20 and 31 if you want to resize.

.social-sharing span{display: inline-block;font-size: 110%;}
.social-sharing span.top, .social-sharing span.bottom {width:100%;} .social-sharing span.right {display: inline;}
