// Responsive image
//
// Keep images from scaling beyond the width of their parents.
.img-responsive(@display: block) {
  display: @display;
  width: 100% \9; // Force IE10 and below to size SVG images correctly
  max-width: 100%; // Part 1: Set a maximum relative to the parent
  height: auto; // Part 2: Scale the height according to the width, otherwise you get stretching
}


// Retina image
//
// Short retina mixin for setting background-image and -size. Note that the
// spelling of `min--moz-device-pixel-ratio` is intentional.
