title: Bootstrap: img-responsive vs img-fluid
body: <p>I am using bootstrap 3.3.6 and I am using class img-responsive for image responsiveness.</p>
  
  <p>I have found a new class name img-fluid, but it's not present in 3.3.6 version.</p>
  
  <p>Can anyone tell what is the difference between img-responsive and img-fluid?</p>
  
  <p>img-responsive just resizes the image as per parent container size which we can achive it using css property width: 100% and height: auto. Then why to use imag-responsive class?</p>
