Web SDK not responsive on smaller devices.

[chaosifier]

Currently I'm working on a Xamarin based project, but since Khalti's SDK isn't available for Xamarin, we have been forced to use Khalti's Web SDK inside a WebView. But since, the payment page isn't responsive, it has become almost impossible to use Khalti with our app. Meanwhile I'm also working on Khalti plugin for Xamarin.Forms, Xamarin.iOS and Xamarin.Android using C# bindings, and will be publishing it under MIT license once done. But for now, it would be great if you could fix this particular issue.
