        }

        private void Window_MouseWheel(object sender, MouseWheelEventArgs e)
        {
            // Check the direction of the scroll
            if (e.Delta > 0) // Scrolling up
            {
                ZoomIn();
            }
            else // Scrolling down
            {
                ZoomOut();
            }

            // Mark the event as handled to prevent further processing
            e.Handled = true;
        }

        private void ZoomIn()
        {
            zoomFactor += 0.1;
            webView.CoreWebView2.ZoomFactor = zoomFactor;
        }

        private void ZoomOut()
        {
            zoomFactor = Math.Max(0.1, zoomFactor - 0.1); // Prevent zooming out too much
            webView.CoreWebView2.ZoomFactor = zoomFactor;
        }
    }
}
