Hi Chris

Question: We want three floated images per row. In the media query, create a pseudo-class selector that targets the fourth img child element first, then every third img that follows. Then, add a clear property that clears the left float.

Okay, we have to set three images to be floated, target is fourth img child element first and then every third img. I guess something like this below.

/* Write the CSS in the media query below */

@media (min-width: 607px) {
    img {
    float: left;      
  }  
    img:nth-child(3n + 4){
    clear: left;
  }
}

More Information: https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-child

@media (min-width: 607px) {

img{ float: left;

}

img:nth-child(3n+4){ clear:left;

}

}
