title: With CSS, can I increase the contrast of background-image upon hover?
body: <p>I have looked into other threads about this, but they all suggest to play around with opacity and tranparency. </p>
  
  <p>But I want to do the opposite: <em>increase</em> contrast of background image (while using the same BG image), or some other way of achieving something similar.</p>
  
  <p>Thanks a lot in advance. Regards</p>
