You just need to add these properties to an image: ```css 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%`. ```js assert(getComputedStyle($('.responsive-img')[0]).maxWidth === '100%'); ``` Your `responsive-img` class should have a `height` set to `auto`. ```js assert(code.match(/height:\s*?auto;/g)); ``` # --seed-- ## --seed-contents-- ```html freeCodeCamp stickers set freeCodeCamp stickers set ``` # --solutions-- ```html freeCodeCamp stickers set freeCodeCamp stickers set ```
