I need my image the size of the page: .backgroundr { padding: 20%; position: absolute; opacity: 0.1; max-width: 100%; max-height: 100%; background-size: cover; background-position: center 100%; }

int main(int argc, char** argv) {
  // Create a file reader
  cv::VideoCapture cap;
    
  // Open the video file
  cap.open(0);
    
  // Create a window to display the video
  cv::namedWindow("Video");
    
  // Show the image in the window
  cv::imshow("Video", video);
    
  // Wait for the user to press a button
  cv::waitKey(0);
}
