I can't figure out what I'm doing wrong in my code

In styles.css, below the body style rule, create a new style rule for the img selector the sets a maximum width of 100% and sets the display value to block. 14 /* Style rule for body and images */ 15 body { 16 background-color: #e4f1f6; 17 } 18 19 img { 20 max-width: 100%; 21 display: block; 22 }
