Challenge: Make an Image Responsive

Link to the challenge:

Is your browser zoom set to 100%? Have you tried a different browser?

your declaring the img twice you have your class call and img call, you class call is correct but you have a defined img width, take away the img style img {width : 600px} and it should work
