--description--

Making images responsive with CSS is actually very simple. You just need to add these properties to an image:

img {
  max-width: 100%;
  height: auto;
}

The max-width of 100% will make sure the image is never wider than the container it is in, and the height of auto will make the image keep its original aspect ratio.

--instructions--

Add the style rules to the responsive-img class to make it responsive. It should never be wider than its container (in this case, it's the preview window) and it should keep its original aspect ratio. After you have added your code, resize the preview to see how your images behave.

--hints--

Your responsive-img class should have a max-width set to 100%.

assert(getComputedStyle($('.responsive-img')[0]).maxWidth === '100%');

Your responsive-img class should have a height set to auto.

assert(code.match(/height:\s*?auto;/g));
