Why use such generic css selector for buttons?

	.btn-group-xs > .btn, .btn-xs {
	padding: .35rem .4rem .25rem .4rem;
	font-size: .875rem;
	line-height: .5;
	border-radius: .2rem;
	}

Sorry if I'm missing something, but why is such a generic css selector as .btn-group-xs > .btn, .btn-xs used? This is changing some of our other UI elements which we don't want changed. Could this be changed to use a different selector which only picks up the correct elements for this plugin?

We love this plugin otherwise, so thanks for making it open source 👍

Thanks.
