// This is purposefully opt-in via an explicit class rather than being the default for all `&lt;img&gt;`s.
// We previously tried the &quot;images are responsive by default&quot; approach in Bootstrap v2,
// and abandoned it in Bootstrap v3 because it breaks lots of third-party widgets (including Google Maps)
// which weren't expecting the images within themselves to be involuntarily resized.
