title: Play button over responsive image using css
body: <p>I'm trying to display play button over responsive image. Button have 96x96px and need to be at center of image.</p>
  
  <p>I tried many methods but always is bad. I read something about flex design, maybe it's simple to do in flex?</p>
  
  <p>I need really simple method because there will be 5 to 10 elements.</p>
  
  <p>Thanks and regards</p>
