Inserting a logo/icon onto a banner with custom code

I would like to put a small Icon logo in the center of the first banner on the homepage of https://www.halcyonholdingsllc.com/.

I tried to inject the following custom code on the advanced tab in the banner/page settings.

.desc-wrapper {
	background-image: url(Icon-White.png);
	background-size: 220px 40px;
	background-repeat: no-repeat;
	background-position: center;
	background-position: center;
}

I've also attached a photoshoped image of what I am trying to do.

Any help would be greatly appreciated! 

Thanks so much! :)
