   1 // Responsive images (ensure images don't scale beyond their parents)
   2 //
   3 // This is purposefully opt-in via an explicit class rather than being the default for all `<img>`s.
   4 // We previously tried the "images are responsive by default" approach in Bootstrap v2,
   5 // and abandoned it in Bootstrap v3 because it breaks lots of third-party widgets (including Google Maps)
   6 // which weren't expecting the images within themselves to be involuntarily resized.
