// Image Mixins

// Responsive image
//
// Keep images from scaling beyond the width of their parents.

    display: $display;
    width: 100% \9; // Force IE10 and below to size SVG images correctly
    width: 100%;
    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.
