Add circle behind my icons?

Managed to add circle behind my icons, but they won’t shop up on mobile devices. Any clue?

This is the css I’ve used

#top .avia-font-fontello, body .avia-font-fontello, html body [data-av_iconfont=”fontello”]:before
{
background-color: white;
border-radius: 50%;
border: 1x solid grey;
padding:20px;
text-align: center;
}
