I tried this:
but the cursor still shows.
You can use a ResouceInterceptor and manipulate the page on the fly to insert custom CSS.
EDIT:
The following implementation should do the job. (It assumes there is a text.css file)
class ManipulatingResourceInterceptor : IResourceInterceptor
{
public ResourceResponse OnRequest(ResourceRequest request)
{
Stream stream = null;
//do stream manipulation
if (request.Url.ToString() == "http://your.web.url/test.css")
{
WebRequest myRequest;
myRequest = WebRequest.Create(request.Url);
Stream webStream = myRequest.GetResponse().GetResponseStream();
StreamReader webStreamReader = new StreamReader(webStream);
string webStreamContent = webStreamReader.ReadToEnd();
stream = webStream;
string extraContent = "*{cursor: none;}";
webStreamContent += extraContent;
byte[] responseBuffer = Encoding.UTF8.GetBytes(webStreamContent);
// Initialize unmanaged memory to hold the array.
int responseSize = Marshal.SizeOf(responseBuffer[0]) * responseBuffer.Length;
IntPtr pointer = Marshal.AllocHGlobal(responseSize);
try
{
// Copy the array to unmanaged memory.
Marshal.Copy(responseBuffer, 0, pointer, responseBuffer.Length);
return ResourceResponse.Create((uint)responseBuffer.Length, pointer, "text/css");
}
finally
{
// Data is not owned by the ResourceResponse. A copy is made
// of the supplied buffer. We can safely free the unmanaged memory.
Marshal.FreeHGlobal(pointer);
stream.Close();
}
}
return null;
}
public bool OnFilterNavigation(NavigationRequest request)
{
return false;
}
}
