Using with Bootstrap

You can use this uploader with Bootstrap framework without writing much additional CSS. Just add the following CSS to your page to hide the browser's "browse" button:

#id-of-uploader .btn {
	cursor: pointer;
	display: inline-block;
	position: relative;
	overflow: hidden;
}

#id-of-uploader .btn input {
	top: -10px;
	right: -40px;
	z-index: 2;
	position: absolute;
	cursor: pointer;
	opacity: 0;
	filter: alpha(opacity=0);
	font-size: 50px;
}
