Customize style of QR

Based on the document on the Wechat Open Platform, you can customize the style of the QR code image by providing the URI of your css file. That means you need to create a css file in the public folder and provide the URI to the css prop.

An example of css file is following:

.impowerBox .qrcode {
  width: 200px;
}
.impowerBox .title {
  display: none;
}
.impowerBox .info {
  width: 200px;
}
.status_icon {
  display: none;
}
.impowerBox .status {
  text-align: center;
}
